Optical amplification in silicon photonic integrated circuits remains a challenge and
stimulated Raman scattering has been proposed as a means of achieving optical gain in …

We experimentally and theoretically study self-phase modulation by Kerr effect in a liquid
filled hollow core photonic crystal fiber. We perform a complete characterization of the linear …

We consider the Raman amplification problem for silicon waveguides in the regime in which
both the pump and signal pulses are relatively short but wide enough that their duration …

We present innovative structures for ring-based Raman amplifier with two separate
entrances for the pump and signal. In this way, only the pump is coupled into the ring and …

In this paper, we investigate the enhancement of Raman amplification bandwidth with self
phase modulation (SPM) effect in silicon based photonic crystal waveguides. The Maxwell …

In 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 …

In this paper, first the improvement in the Raman amplification bandwidth through the self-
phase modulation (SPM) effect in the straight photonic crystal structures was compared to …

In this paper, we present new structures based on ring, conventional photonic crystal and
hybrid PhC for enhanced Raman amplification. The structures consist of two separate …

Les travaux de cette thèse apportent une contribution théorique et expérimentale aux études
portant sur les cristaux photoniques planaires à fente pour l'exaltation locale du champ …

Dans ce travail de thèse, nous avons étudié des effets d'optique non-linéaire d'ordre trois
dans les cavités à cristaux photoniques en silicium. Le premier d'entre eux est un …
