Texto completo da fonteOn chips optical nanocavities have become useful tools for trapping and manipulation of colloidal objects. In this thesis we study the nanocavities as building blocks for optical forces, trapping and handling of particles. Proof of concept of trapping dielectric microspheres appears as the starting point of the development of lab on chip. In the first chapter we go through the literature of optical forces in free space and integrated optics. The second chapter presents the experimental tools for the characterization of nanocavities and the set-up developed to perform optical measurements with the colloidal particles. The third chapter describes the proof-of-concept trapping of polystyrene particles of 500 nm, 1 and 2 µm. In the following chapter we analyze the particle trapping as function of the injected power into the cavities. The chapter five gives some examples of the possibilities of particles handling functions with coupled cavities. Eventually, in the last chapter we show assemblies of particles on different geometry of cavities studied in this thesis

Texto completo da fonteThis thesis is devoted to the experimental study of optical processing functions, of wavelength multiplexed (WDM) or time multiplexed (OTDM) signals, based on III-V semiconductors photonic crystals (PhC) devices produced in the European project Copernicus. The unique dispersive properties that is possible to obtain in such a structure were studied through nonlinear effects enhanced in slow light regime. Thus, a study of four-wave mixing was performed with high bit rate wavelength conversion and time demultiplexing applications. Moreover, second harmonic generation has been demonstrated with record efficiency for such a structure, and applied to 42.5 Gbit/s telecom signals monitoring. PhC nanocavities were used as wavelength drop filter to demonstrate 100 Gbit/s WDM signal demultiplexing. Thereafter, we worked on hybrid photonic platform. The heterogeneous integration of III-V PhC nanocavity on silicon waveguide allowed us to perform very fast optical switching, applied to wavelength conversion up to 20 Gbit/s and power limiting function at 10 Gbit/s. All of these results are very promising for future photonic integration with micro-electronics and CMOS technology. Through this work, we show that PhC, owing to their confinement and slow light properties, are structures particularly interesting to perform optical processing functions

Texto completo da fonteBright and tunable sources of indistinguishable single photons are key devices for photonic quantum information technologies. Building such a source with a semiconductor quantum dot (QD) requires a “knob” to tune the QD emission wavelength combined with a broadband photonic structure for light extraction. This thesis reports several important steps towards this goal.We first investigate a nanocylinder cavity, a photonic structure that, despites its simplicity, offers a pronounced Purcell acceleration of spontaneous emission over a large spectral bandwidth. We demonstrate the first resonant optical spectroscopy of a QD embedded in a nanopost cavity, by leveraging a cross-polarization scheme that efficiently suppresses stray laser light (collaboration with the group of Richard Warburton). This technique enabled a precise characterization of the optical properties of the emitter.We next demonstrate a tunable single-photon source based on a QD embedded in a tapered photonic wire. In our device, a set of on chip electrodes biased with a DC voltage applies an electrostatic force to the wire. As the wire bends, the resulting mechanical strain changes the bandgap energy of the embedded QDs. We demonstrate both a large increase and a large decrease of the QD emission wavelength by controlling the wire bending direction.With an AC voltage, the above-mentioned actuation scheme can also excite the vibration modes of the nanowire. This capability is interesting in the context of hybrid nanomechanics. In our experiments, we leverage the QD photoluminescence to detect and identify the wire mechanical vibrations. In particular, we evidence a high-order flexural mode that resonates at 190 MHz, a value that exceeds the QD radiative rate. This constitutes an important step towards the spectrally-resolved-sidebands regime.The devices demonstrated in this work open promising prospects for the future developments of quantum photonics and hybrid nanomechanics

Texto completo da fonteIn this thesis, we studied third order nonlinear optical effects in photonic crystal cavities. The first of those effects is is the phenomenon of high frequency (GHz) self-pulsing in these cavities, which originates from a modulation of the transmission of the cavity due to the interaction between the free-carrier dispersion and the two-photon absorption. We have observed these self-induced oscillations for the first time in silicon photonic crystal nanocavities, with a frequency of about 3 GHz and a high spectral purity. We have developed a model to analyze the mechanisms that govern the onset of these oscillations, as well as the amplitudes of the fundamental and harmonic frequencies of these oscillations. This self-pulsing phenomenon would allow us to realize realize ultra-compact microwave sources made of silicon. The second phenomenon studied is that of Raman scattering, which is the only way to obtain lasers fully in silicon demonstrated so far. The Raman scattering was measured first in narrow photonic crystals waveguides (W0.63) of length 100 microns, where we could obtain a number of Stokes photons up to 9, showing that the stimulated Raman scattering predominated in these waveguides, although we have not been able to obtain a true Raman laser effect in them. We then measured the Raman scattering in doubly resonant nanocavities specifically designed from these waveguides to optimize the Raman effect, with quality factors up to 235000 for the Stokes resonance. Although we could only measure spontaneous Raman scattering in these cavities, with a Purcell factor of 2.9, the theoretical study that we conducted on the Raman lasers, which agrees perfectly with the experimental results, shows that it would be possible to obtain a Raman laser in these cavities with a threshold below the milliwatt, provided we reduce the losses due to the free-carrier absorption. This could be accomplished by decreasing the free-carrier lifetime, for example by removing the free carriers from the silicon using a MSM junction
