Abstract:
We report on the spectroscopic magnetooptical studies of spin dynamics in diluted magnetic semiconductor (DMS) GaAs / AlGaAs / ZnSe / ZnCdMnSe heterovalent double quantum wells (QW). The transients of circularly polarized photoluminescence in an external magnetic field are detected in the structures with different widths of the GaAs QW. The analysis of the data, performed within the rate-equation model, has allowed separate estimations of the spin relaxation rate of localized electrons and holes. The spin flip of the electrons confined in the DMS ZnCdMnSe QW is faster than 20 ps, whereas the spin flip of the heavy hole localized in the GaAs QW is as long as ~9 ns. The long spin flip of the holes is presumably governed by their strong 3-dimensional localization.

Abstract:
A subwavelength sized source or detector of visible light can be raster scanned in close proximity to the surface of a sample to generate images at a resolution well beyond the classical diffractional limit. Applications of the resultant technique, near-field scanning optical microscopy (NSOM), include fluorescence imaging of fixed cells, mode profiling of semiconductor lasers, and high density magnetooptic data storage. The focus of this presentation, however, will be on the more recent use of NSOM in the identification and characterization of discrete quantum emitters from within an ensemble.Two such systems will be discussed. The first involves the detection and characterization of single fluorescent molecules. The usual difficulty with single molecule detection is not the inherently weak luminescence signal from each molecule, but rather the large background from impurity luminescence and Raman scattering within the excitation volume. NSOM greatly reduces this volume and hence the resultant background, yielding sensitivity of 0.005 molecules.

Abstract:
ABSTRACTIn accord with the Drude model, the free-carrier contribution to the dielectric function at infrared wavelengths is proportional to the ratio of the free-carrier concentration N and the effective mass m*, and the product of the optical mobility μ and m*. Typical infrared optical experiments are therefore sensitive to the free-carrier mass, but determination of m* from the measured dielectric function requires an independent experiment, such as an electrical Hall-effect measurement, which provides either N or μ. Highly-doped zincblende III-V-semiconductors exposed to a strong external magnetic field exhibit non-symmetric magnetooptical birefringence, which is inversely proportional to m*. If the spectral dependence of the magnetooptical dielectric function tensor is known, the parameters N, m* and μ can be determined independently from optical measurements alone. Generalized ellipsometry measures three complex-valued ratios of normalized Jones matrix elements, from which the individual tensor elements of the dielectric function of arbitrarily anisotropic materials in layered samples can be reconstructed. We present the application of generalized ellipsometry to semiconductor layer structures at far-infrared wavelengths, and determine the magnetooptical dielectric function for n-GaAs and n-AlGaInP for wavelengths from 100 μm to 15 μm. We obtain the effective electron mass and mobility results of GaAs in excellent agreement with results obtained from Hall-effect and Shubnikov-de-Haas experiments. The effective electron mass in disordered n-AlGaInP obtained here is in very good agreement with previous k·p calculations. (Far)-infrared magnetooptic generalized ellipsometry may open up new avenues for non-destructive characterization of free-carrier properties in complex semiconductor heterostructures.

ABSTRACTWafer bonding of a magnetooptic garnet crystal to III-V compound semiconductor and LiNbO3 is discussed for the application to waveguide optical isolators. Two types of waveguide isolators, an interferometric isolator and a semileaky isolator, are discussed. The interferometric isolator uses nonreciprocal phase shift and is composed of the GaInAsP guiding layer. The isolator has the advantage of integratability with optical active devices. The semileaky isolator composed of a magnetooptic garnet guiding and LiNbO3 upper cladding layer has the advantages of large fabrication tolerance and wide operating wavelength range. The performance of isolators is also demonstrated.

AbstractRecent advances in the techniques for preparation of Ce-doped yttrium iron garnet (YIG) films on gadolinium gallium garnet (GGG) and semiconductor substrates, hybrid material structures of YIG/GGG- gallium arsenide (GaAs) combination, and the resulting microwave and guided-wave magnetooptic (MO) devices are presented. For example, high-efficiency MO Bragg cell modulators using the YIG/GGG-alumina material structure have been realized using a non-uniform bias magnetic field as well as an electronic feedback. Such MO modulators are being used to construct integrated optic devices such as optical scanners, switches, and frequency shifters. Also, a wideband microwave bandstop filter with a carrier frequency tuning range as high as 2.5 to 23.0 GHz using the YIG/GGG-GaAs material structure has been realized. The same material structure can be employed to perform MO Bragg diffraction experiment at ultrahigh carrier frequencies.

Abstract:
AbstractAll of the materials necessary for integrated isolators were grown and the application of 2D photonic crystal structures to isolators has been explored. Magnetooptical garnets were grown monolithically by reactive rf sputtering. MgO was used as a substrate because it will useful for future buffer layers and optical claddings. The chemical, structural, and optical properties of the resulting films were analyzed. In order to incorporate photonic crystal structures into the magneto-optic integration scheme, we have calculated a range of radii and spacings necessary to fabricate YIG/air structures with 2D photonic bandgaps using an advanced plane-wave expansion technique. Selfassembled alumina nanostructures have been grown with similar symmetries as those calculated, namely hexagonal close-packed pores. These nanostructures were grown onto semiconductor and oxide substrates in order to demonstrate their use as RIE masks in fabricating photonic crystals. The nanostructures can also be transferred into YIG using separate alumina masks. However, the actual structures grown in this work were smaller than those required for telecommunications due to power supply limitations. For biasing the magneto-optical elements, sputtering was used to monolithically integrate permanent SmCo magnet films using semiconductor-friendly processing. These magnets were sufficient for biasing our magneto-optical waveguides. The chemical, structural and magnetic properties of these materials, as well as total integration with SiO2 cladding layers were analyzed.

Abstract:
AbstractSeveral experimental methods: absorption, photoemission and transport measurements were used to determine the energy position of substitutional Fe2+ (3d6) donor state in the band structure of the semimagnetic semiconductor Hg1-v-xCdvFexSe for 0≤v≤0.7 and v+x=l, and x≤0.15. For v≤0.40, Fe2+(3d6) level is a resonant donor located in the conduction band. For v=O (HgSe) we obtain 230 meV for the position of Fe2+(3d6) level with respect to the bottom of the conduction band which coincides with the position of the Fermi level for electron concentration N ≅5x1018 cm-3. Surprisingly, the mobility of free electrons (T∼4.2K) is abnormally high and the Dingle temperature measured in quantum magnetoresistivity oscillations (SdH effect) and magnetooptical measurements is abnormally low. Because of the Coulomb interaction between the ionized donors, at low T, there will appear some correlation of their positions. This may lead to a kind of “liquefying” of the system of ions and to its “crystallisation” (i.e. formation of a superlattice or hyperlattice of ionized donors) at even lower T. The space-ordering of ionized donors influences dramatically the free-carrier scattering and correspondingly explains the high mobility and low Dingle temperature. Finally, we shall also present some magnetic properties of these new semimagnetic materials.

Abstract:
ABSTRACTPhotonic integration has proved remarkably successful in combining multiple optical devices onto a single chip with the benefits of added functionality, and reduction in costs, arising from the replacement of manual assembly and alignment of individual components with lithographic techniques. However, the incorporation of optical isolators and related non-reciprocal devices within standard optoelectronic wafer platforms is exceptionally challenging. Preferred magneto-optic materials cannot be exploited as waveguide core layers on semiconductor wafers due to a lower refractive index. Another difficulty is the phase velocity mismatch as a consequence of the inherent structural birefringence associated with waveguide geometries.Our approach to the integration of an optical isolator with a III-V semiconductor laser involves combining a nonreciprocal mode converter with a reciprocal mode converter, based on an asymmetric profiled rib waveguide, fabricated by Reactive Ion Etching. We demonstrate that suitably tapered waveguides can be employed to connect the mode converter to other sections thereby avoiding problems caused by mode-matching and reflections from the section interfaces.The nonreciprocal mode converter is formed from a continuation of the III-V semiconductor waveguide core with a magneto-optic upper cladding so that Faraday rotation occurs through the interaction of the evanescent tail. The phase velocity mismatch due to the waveguide birefringence is overcome using a quasi-phase-matching approach. Lithography is used to pattern the top cladding so that the film immediately on top of the waveguide core alternates between magnetooptic and a non-magneto-optic dielectric of a similar refractive index. Our first demonstrations used a dielectric (silica or silicon nitride) patterned by etching, or lift-off, on top of a GaAs rib waveguide, over which was deposited a magneto-optic film. This film was deposited by sputtering from a Ce:YIG target and demonstrated magnetic hysteresis, but, as it was not annealed, it was believed to consist of Ce:YIG and/or gamma iron oxide microcrystallites embedded in an amorphous matrix. With quasi-phase-matching periods of 110–160 μm and a waveguide length of 8 mm, we were able to demonstrate up to 12% non-reciprocal TE- to TM-mode conversion around a wavelength of 1.3 μm using the remanent magnetisation.In order to enhance the magneto-optic effect it is desirable to anneal such films. However the mismatch in thermal expansion coefficients results in a catastrophic failure of samples with large area film coverage. This problem has been shown to be alleviated by patterning the YIG film. Unfortunately wet-etching of YIG also etches (Al)GaAs and, therefore, the development of a lift-off process for YIG deposition has been undertaken. Initial results are promising with ∼100 μm×2.5 μm YIG sections deposited on a GaAs layer which remain intact after an anneal in an oxygen atmosphere.
