Streszczenie:

Lithium niobate is an excellent optoelectronic and nonlinear material, which plays an important role in integrated optics. However, lithium niobate is difficult to etch due to its very stable chemical nature, and the microstructure of lithium niobate’s metasurface is generally of subwavelength, which further increases its processing difficulty. Here, by using Ar+-based inductively coupled plasma etching and KOH wet etching, we improve the etching quality and fabricate a Fano-resonant metasurface based on lithium niobate on insulator, which has a very high reflectivity of 92% at near-infrared wavelength and the potential of becoming a high-reflectivity film. In addition, to evaluate the practical performance of the metasurface, we constructed a Fabry–Perot cavity by using it as a cavity mirror, whose reflection spectrum shows a finesse of 38. Our work paves the way for the development of functional metasurfaces and other advanced photonic devices based on lithium niobate on insulator.

Low-loss photonic waveguides in lithium niobate offer versatile functionality as nonlinear frequency converters, switches, and modulators for integrated optics. Combining the flexibility of laser processing with liquid phase epitaxy we have fabricated and characterized lithium niobate channel waveguides on lithium niobate and lithium tantalate. We used liquid phase epitaxy with K2O flux on laser-machined lithium niobate and lithium tantalate substrates. The laser-driven rapid-prototyping technique can be programmed to give machined features of various sizes, and liquid phase epitaxy produces high quality single-crystal, lithium niobate channels. The surface roughness of the lithium niobate channels on a lithium tantalate substrate was measured to be 90 nm. The lithium niobate channel waveguides exhibit propagation losses of 0.26 ± 0.04 dB/mm at a wavelength of 633 nm. Second harmonic generation at 980 nm was demonstrated using the channel waveguides, indicating that these waveguides retain their nonlinear optical properties.

Streszczenie:

High-quality epitaxial growth of thin film lithium niobate (LiNbO3) is highly desirable for optical and acoustic device applications. Despite decades of research, current state-of-the-art epitaxial techniques are limited by either the material quality or growth rates needed for practical devices. In this paper, we provide a short summary of the primary challenges of lithium niobate epitaxy followed by a brief historical review of lithium niobate epitaxy for prevalent epitaxial techniques. Available figures of merit for crystalline quality and optical transmission losses are given for each growth method. The highest crystalline quality lithium niobate thin film was recently grown by halide-based molecular beam epitaxy and is comparable to bulk lithium niobate crystals. However, these high-quality crystals are grown at slow rates that limit many practical applications. Given the many challenges that lithium niobate epitaxy imposes and the wide variety of methods that have unsuccessfully attempted to surmount these barriers, new approaches to lithium niobate epitaxy are required to meet the need for simultaneously high crystalline quality and sufficient thickness for devices not currently practical by existing techniques.

Lithium niobate-silica fibers were produced by the combination of the sol-gel method and the electrospinning technique. Two sol-gel solutions starting from niobium-lithium ethoxide and tetraethyl orthosilicate were prepared and then mixed with polyvinylpyrrolidone; the solutions were electrospun in a coaxial setup. The obtained lithium niobate-silica polymeric fibers were approximately 760 nm in diameter. Raman spectroscopy confirmed the composite composition by showing signals corresponding to lithium niobate and silica. Scanning electron microscopy showed coaxial fibers with a diameter of around 330 nm arranged as a fibrillar membrane at 800 °C. At 1000 °C the continuous shape of fibers was preserved; the structure is composed of silica and lithium niobate nanoparticles within the fibers. The formation of crystalline lithium niobate and amorphous SiO2 phase was also confirmed by XRD peaks.

We present the design and fabrication advances on active lithium niobate metasurfaces. We determine by numerical calculations a metasurface design with electro-magnetic resonances in the visible and near-infrared, by taking into account the constraints for fabrication on thin films of lithium niobate. We suggest that the optical properties of the metasurface can be switched using the electro-optical properties of lithium niobate.

This paper describes the cutting characteristics of lithium niobate, which is used for surface acoustic wave type micropumps, regarding the formation of micro grooves by direct cutting. Since lithium niobate is a brittle material with a strong crystal orientation dependency, significant differences were observed in the characteristics of the finished surface according to different directions of cutting. The ductile mode cutting of lithium niobate was found to be feasible with cutting depths of approx. 5 μm or less. Also, results of the study show the feasibility of the formation of minute grooves through the cutting of lithium niobate, using milling with an end mill.

Streszczenie:

Bidomain single crystals of lithium niobate (LiNbO3) and lithium tantalate (LiTaO3) are promising material for usage as actuators, mechanoelectrical transducers and sensors working in a wide temperature range. It is necessary to take into account anisotropy of properties of crystalline material when such devices are designed. Inthis study we investigated deformations of bidomain round shapedY+ 128°-cut wafers of lithium niobate in an external electric field. Dependencies of piezoelectric coefficients on rotation angles were calculated for lithium niobate and lithium tantalate and plotted for the crystal cuts which are used for bidomain ferroelectric structure formation. In experiment, we utilized external heating method and long-time annealing with lithium out-diffusion method in order to create round bidomain lithium niobate wafers. In order to obtain dependencies of the bidomain crystals’ movements on the rotation angle with central fastening and external electric field application optical microscopy was used. We also modeled a shape of the deformed bidomain wafer with a suggestion that the edge movement depends on the radial distance to the fastening point quadratically. In conclusion, bidomainY+ 128°-cut lithium niobate wafer exhibits saddle-like deformation when DC electric field is applied.

The Gibbs energy of the borates formation of trace amounts of metallic impurities (Al4B2O9, CaB2O4, CaB4O7, Ca2B2O5, Ca3B2O6, PbB2O4) in the lithium niobate charge is calculated. It is shown that the element boron, as an active complexing agent, in the composition of the B2O3 flux can prevent the transition of impurity metals, inevitably present in trace amounts in the charge of lithium niobate, into the structure of the lithium niobate crystal.

Streszczenie:

Lithium niobate thin film represents as an ideal material substrate for quantum photonics due to its strong electro-optic effect and high-speed modulation capability. Here, we propose a novel platform which heterogeneously integrates single self-assembled InAs/GaAs quantum dots for a single-photon source on a lithium niobate photonic chip. The InAs/GaAs quantum dots can be transferred to the lithium niobate waveguide via a substrate transfer procedure with nanometer precision and be integrated through van der Waals force. A down-tapered structure is designed and optimized to deliver the photon flux generated from the InAs quantum dots embedded in a GaAs waveguide to the lithium niobate waveguide with an overall efficiency of 42%. In addition, the electro-optical effect is used to tune, and therefore to tune the beam splitting ratio of the integrated lithium niobate directional coupler, which can simultaneously route multiple photons to different spatial modes, and subsequently fan out through grating couplers to achieve single-photon sub-multiplexing. The proposed device opens up novel opportunities for achieving multifunctional hybrid integrated photonic chips.

This thesis presents the results from an investigation into methods for micron-scale relief structuring of lithium niobate. A wet etch consisting of HF and HNO3 was applied, and directed by 1) patterning the ferroelectric domain structure of the samples and 2) illuminating the crystals with patterned 488nm light. Post-etch treatment of the structures resulted in ridge waveguides and alignment grooves, while pre-etch manipulation achieved an etch-stop. Ablation was investigated as a method of directly structuring the crystal and for patterning photoresist. The etch was found to leave the +z face untouched. The -z face was etched at a rate, k, in µm/hour given by k = e 20.37 - 6300/T where T is the absolute temperature. This differential etch rate reveals a pattern induced in the ferroelectric domain structure by the technique of electric field patterning. The structures had walls with roughness < 5nm. Straight walls were easily achieved aligned along the y-direction at 120o to this. Other directions can result in facetted walls. Ridge waveguide losses <1dBcm-1, fibre alignment grooves and an etch stop were demonstrated using appropriate pre- and post-etch treatments. The etch was found to be affected by illumination with 488nm radiation. In Fe:LiNbO3 complete and partial frustration of the etch was induced on the -z face. Characteristic features of the partial frustration were sub-micron ridges and triangular pillars, separated by gaps as small as 500nm. In LiNbO3 the etch rate was found to increase on the -z face. The etch rate on the +z face was unaffected in both. Direct ablation with an excimer laser produced relief structures. Aspect ratios > 1:1 resulted in a dendritic structure in the ablated area. Direct ablation was suitable for patterning the photoresist. Surface damage was intentionally induced when producing large (>100µm) openings, however, the effect of surface damage on electric field poling could not be conclusively tested. Submicron openings were also created and subsequent poling produced sub-micron domains, revealed by etching.

A class of integrated optical devices is based on light propagation in optical channel waveguides. It includes optical modulators such as the integrated Mach-Zehnder (IMZ). Many applications have been proposed for such integrated optical devices. The present work was motivated by a proposed application to voltage determination on high voltage lines, for example, SF₆ bus ducts in Hydro substations. For the voltage measurement application two device types were proposed. The first includes devices using capacitive voltage dividers. A novel divider for the SF₆ bus duct application was proposed using a LiNbO₃ wafer into which an IMZ could be built to give an integrated unit. Time permitted the divider to be tested only using a separate IMZ. The second type of device includes Immersion devices. Two novel immersion devices are proposed and their theory is developed. IMZs were made for the demonstrated, high voltage sensor, by diffusing Ti into LiNbO₃. Much effort was put into solving a sequence of experimental obstacles including the elimination of Li₂O out-diffusion (which causes a waveguide to be produced on the whole surface), the polishing of the LiNbO₃ crystals and optical fibers, and the butt coupling of the fibers to the crystals. In the end IMZs were fabricated with state-of-the-art extinction ratios. A third device, employing voltage induced waveguides, was proposed and was demonstrated. A mathematical treatment of the theory of the IMZ is provided.

In this thesis, electron paramagnetic resonance (EPR) was utilized in measuring and characterizing the dopant ions in three samples of lithium niobate (LiNbOâ‚ƒ). The first sample was LiNbOâ‚ƒ of congruent composition doped with 0.25% mol chromium (LiNbOâ‚ƒ:Cr). This sample was studied in detail using two microwave frequencies, 9.4 GHz and 34.4 GHz. It was also studied both at room temperature and at 10 K. Several centers including complexes of Cr-Cr pairs were observed in addition to the most prevalent axial CrÂ³âº center. The other two samples were LiNbOâ‚ƒ:Mg:Fe, one of congruent composition and the other of stoichiometric composition. The congruent composition contained 6% mol Mg and 0.02% mol Fe, while the stoichiometric sample contained 0.45% mol Mg and 0.01% mol Fe. The stoichiometric composition contains all the same centers observed in the congruent material, plus two additional centers. Since the stoichiometric material provides EPR spectra of much higher resolution, those centers existing in both compositions were characterized more accurately from the stoichiometric material. A discussion of models for dopant center symmetries, dopant positions in the LiNbOâ‚ƒ lattice, and the charge compensators required by each center is provided. It is shown that charge compensators play an important role in explaining the existence of the additional centers observed in the stoichiometric material.

Streszczenie:

The rapid advancement in electronic industries is driven by variety in electronic and electrical miniaturization concept design. Enhancement in performance, for example better scaling, stable response, less performance fatigue and miniaturization is at the heart or global research interest. Consistent with this concept, this research targets the development of a ferroelectric composite comprising inorganic ferroelectric and ferroelectric polymer, with potential for applications as the gate in ferroelectric fielq effect transistors. The inorganic ferroelectric material in this research was lithium niobate. Lithium niobate is known to have a high Curie temperature and low permittivity value. Even though lithium niobate (LiNbO3) possesses very good ferroelectric properties there are relatively few instances in which these properties are exploited in terms of composites. nus first research stage was to investigate the preparation of LiNb03 nanocrystals for use in a thin film nanocomposite. This stage describes the preparation and characterization of LiNbO3 nanoparticles. LiNbO3 has been prepared successfully via a molten salt route at 6500c using lithium chloride and lithium carbonate as a flux and niobium oxide as niobium source. This resulted in a very high crystallinity with nanocrystals on average 90 - 120 nm in diameter. The study also analyzed the optimum degree of crystallinity in the ferroelectric polymers, PVDF and P(VDF-TrFE). In order to achieve high crystallinity in PVDF and its copolymer, the spin coated polymer substrate needs to be annealed to a certain temperature. The optimum temperature to ensure the , highest crystallinity is found to be in the range 1300c - 140"C. Vacuum annealing also increased the crystallinity to a certain degree. The properties of a composite mixture between polymer P(VDF-TrFE) and LiNb03 were studied to understand its ferroelectric characteristics. The composite, with 0-3 connectivity, was processed using 3 different types of surface active agents; silane, poly (acrylic acid co-maleic acid) and a commercial deflocculant, KD!. A microstructure study showed only sUane provided strong binding between the matrix and LiNbQ3 particles. Polarization - electric field (P-E) hysteresis loops proved to be unsaturated; however a calculation showed that only 40% of the applied voltage was applied to the LiNbO3 particles, because of difference in permittivity values of each constituent hence the coercive field was not exceeded. The composite permittivity was also graphically fitted to a theoretical formula (Lichtenecker and Yamada) to understand its microstructure pattern connectivity.

This thesis describes the research carried out to develop several novel periodically poled lithium niobate (PPLN) devices. These devices exploit the ability to invert micro-domains of spontaneous polarisation in ferroelectrics such as lithium niobate. The fabrication of PPLN devices is described and extensive studies into factors influencing the poling quality are presented. In particular a comparison of material properties of unprocessed lithium niobate material from a range of different suppliers is carried out. Several novel PPLN devices are reviewed and two main devices are investigated - an electro-optically controlled Bragg grating modulator for laser beam switching and modulation and a titanium indiffused waveguide in PPLN for frequency conversion. The design, fabrication and operation of the electro-optic Bragg modulators is described and results for the first infrared operation at 1064nm of such a device are presented. Several discrepancies are seen between experimental results, both in this thesis and previously published results, and a theoretical model based on Kogelnick?s coupled wave analysis. These anomalies are further investigated at visible operation (633nm and 488nm) and solutions and methods for alleviating the discrepancies are presented. Work on titanium indiffused channel waveguides in PPLN is reported, including a study into fabrication issues and the demonstration of second harmonic generation of 416nm in such a device.

Streszczenie:

Le niobate de lithium (LN), en raison de ses propriétés, électro-optiques, optiques non linéaires et photoréfractives (PR) , s'impose comme un matériau de choix pour des applications en modulation, filtrage, stockage holographique ou conversion de fréquence optique. L'effet PR est gouverné à la fois par les centres profonds extrinsèques (Fe2+ et Fe3+ le plus souvent) et par les antisites niobium en site (Nbli5+), qui constituent des pièges préférentiels pour les électrons arrachés aux donneurs profonds et forment ainsi des polarons liés Nbli4+, caractérisables par une large bande d'absorption photo-induite (API) s"étendant dans le rouge et le proche infrarouge, ainsi que par une bande de photoluminescence (PL) légèrement décalée en longueur d'onde par rapport à la précédente. Nous présentons ici une étude expérimentale de la PL polaron dans le LN congruent dopé fer, fonction de la température et de l'intensité lumineuse excitatrice, en régime continu et en régime pulsé, ainsi qu'un modèle phénoménologique à trois centres permettent d'interpréter toutes les caractéristiques observées. Nous montrons que la PL permet en principe de doser les donneurs profonds dans le LN congruent en qualité infime, que soit leur nature. Pour les ions Fe2+, la détectivité est typiquement de 0,25 ppm à l'ambiante, ce qui est bien meilleur que la spectroscopie d'absorption. La PL résolue spatialement permet en outre, contrairement aux autres techniques, de cartographier la concentration de donneurs profonds à l'échelle micrométrique, d'où son potentiel pour la caractérisation de guides d'onde, de composants optiques intégrés ou autres microstructures
Because of their electro-optical, non-linear optical and photorefractive effet, lithium niobate crystals (LN) are used in many applications such as modulation, filtering, holographic storage or frequency conversion. Its known that the photorefractive effect is influenced by both extrincic deep centers (Fe2+ and Fe3+ in most cases) and by niobium antisites (Nbli5+) which constitute preferential sites to trap an electron hence giving a small bound polaron (Nbli4+). This defect is characterized by a photo_indiced obsorption (API) broad band in the NIR range, as well as slightly Stokes shifted photoluminescence band (PL). We presnt nerein an experime,tal study of the polaron related PL in iron doped congruent lithium niobate as a function of temperature and incident intensity in CW and pulsed regime. We also propose a phenomenological threecenter model as an interpretation of all observed results. We show that the PL permits one to determine the concentration of deep centres in congruent LN in trace amounts, whatever their nature. For Fe 2+ ions, the sensitivity is typically around 0,25 ppm at RT, which is better than absorption spectroscopy. In addition, unlike other techniques, the PL is spatially resolved (micrometer scale) which allows to maps the concentration of deep donors, hence its potential for characterizating waveguides, integrated optical components and other microstructures

Streszczenie:

The influence of illumination on ferroelectric domain engineering in lithium niobate and lithium tantalate is investigated. The conventional method of domain inversion is electric field poling, which suffers from several limitations such as a requirement for photolithography and high-voltage equipment, the formation of inhomogeneous electric fields, and a minimum domain size of micrometres. Through the use of directed laser light, either in the presence or absence of an externally applied electric field, these limitations can be overcome and new fabrication capabilities are revealed. Light-assisted poling is the simultaneous application of an external electric field and laser illumination. Using wavelengths ranging from near-UV to near-IR, the electric field required for domain nucleation was reduced for increasing intensities. This effect was most prominent in crystals highly doped with MgO, achieving a reduction of 90% and 98% for cw and fs-pulsed light, respectively. Arbitrary domain patterns were directly written by the scanning of a focused beam. Periodically poled gratings were formed using periodic intensity patterns via a phase mask, forming domain engineered crystals suitable for quasi-phase-matched nonlinear frequency conversion.
