Control of Spatial Instabilities with Intracavity Photonic Crystals

Abstract

Unwanted spatial instabilities often spoil the quality of the beam in broad area nonlinear optical devices, but a periodic modulation of the refractive index, i. e. a photonic crystal, can be used to control the transverse properties of the emitted light. Due to non-linearity and cavity losses these devices are studied in the context of self-organization. Indeed, for large Fresnel numbers, the emitted beams can exhibit not only temporal instability but also spontaneous pattern formation. Previous analyses of Kerr cavities have shown the possibility to inhibit the phenomenon of pattern formation using photonic crystals [1]. In other words, the instability threshold moves to larger values of the pump. This theoretical prediction has been recently confirmed in two experiments in vertical-cavity surface emitting laser [2] and with a photorefractive medium in single-mirror feedback configuration [3].
