Advanced Diamond Microfabrication for Microoptics and Photonics

Diamond is an exceptional material - hard, stiff, transparent, which makes it ideal for the fabrication of optical and mechanical systems that take advantage of these properties. Diamond is not only "better", but it offers the possibility of integrating br ...

A compact, integrated silicon device for the generation of spectrally filtered, pair-correlated photons

Vincenzo Savona, Momchil Minkov

The third-order nonlinearity of silicon gives rise to a spontaneous four-wave mixing process in which correlated photon pairs are generated. Sources based on this effect can be used for quantum computation and cryptography, and can in principle be integrat ...

Integration of liquid crystals molecules in optofluidic devices

Julien Cuennet

It is in the context of miniaturization that arises the microfluidics concept. It is not uncommon in chemical, biological or medical analysis laboratories to manipulate or to mix fluids while measuring the results with filters, spectrometers or all other e ...

Ultrafast tristable spin memory of a coherent polariton gas

Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Taofiq Paraïso, Roland Cerna

Non-linear interactions in coherent gases are not only at the origin of bright and dark solitons and superfluids; they also give rise to phenomena such as multistability, which hold great promise for the development of advanced photonic and spintronic devi ...

Electronic and Optical Properties of Semiconductor Quantum Dots

Guillaume Jean Tarel

This thesis is devoted to theoretically study the systems of single quantum dots (QDs) embedded in various photonic nanostructures, in close relation with experimental data. The word single is essential: due to their nanometer size, QDs have mainly been st ...

Tunable and Broadband Nanostructured Photonic Devices : Fabrication and Characterization

Pierre-Yves Baroni

The main topic of this thesis is the fabrication and characterization of structures smaller than the wavelength of light, for operation in the visible or near infrared spectral range. In the first part of this thesis, the fabrication of periodic structures ...

Accordabilité de la réponse optique des cristaux photoniques par infiltration de matériaux organiques

Pascale El-Kallassi

Photonic crystals are stuctures in which the refractive index varies periodically on the wavelength scale in one, two or three dimensions. Due to interference effects, these structures can forbid light propagation over a large spectral range called "the ph ...

Nanofluidic tuning of photonic crystal circuits

Demetri Psaltis

By integrating soft-lithography-based nanofluidics with silicon nanophotonics, we demonstrate dynamic, liquid-based addressing and high Δn/n (∼0.1) refractive index modulation of individual features within photonic structures at subwavelength length scales ...

Disorder-induced losses in planar photonic crystals

Romuald Houdré, Rolando Ferrini, Henri Benisty, David Leuenberger

The phenomenological approach introduced by Benisty et al. [Appl. Phys. Lett. 76, 532 (2000)] to model out-of-plane radiation losses in planar photonic crystals with a low vertical refractive index contrast is extended to the case of in-plane disorder. The ...

Étude expérimentale des propriétés optiques des cristaux photoniques bidimensionnels et de leur accordabillité

Barbara Wild

Photonic crystals are periodic dielectric structures, where the periodicity varies in one, two or three dimensions. Analogous to the periodic potential of electrons in semiconductors, the periodic variation of the dielectric constant influences the electro ...

Tuning the optical properties of planar photonic crystals by liquid crystal infiltration

Romuald Houdré, Rolando Ferrini, Libero Zuppiroli, Liza Carol Andrea Dunbar, Barbara Wild

Recently there has been a growing amount of attention devoted to tuneable photonic crystals (PhCs) where the optical response of PhC structures can be dynamically modified. We will show how infiltrating planar PhCs with a synthetic organic material allows ...
