Prospects in Optoelectronic Photonic Crystal Components — •J.-M. Lourtioz — Institut d’Électronique Fondamentale, UMR 8622 du CNRS, Bât. 220, Université Paris-Sud, 91405, Orsay Cedex, France

Photonic crystals (PhC), artificial, wavelength-scale multidimensional periodic structures, have given birth to a number of realizations in semiconductors. Photonic integrated circuits, especially around new integrated lasers are challenging directions of research for miniaturization and new functions in optical telecommunications. After recalling the basic physics behind, we will briefly review some of these applications and underline the current status of this very active research field worldwide. The largest part of the talk will concern the recent advances in λ ≈ 1.5 µ m PhC waveguide lasers in the InP substrate approach. After a brief description of coupled cavity waveguide (WG) lasers and their use for integrated optics, we will mostly focus on canonical PhC WG lasers formed by one or several rows of missing holes in the PhC. Most of the results will be taken from the French RNRT CRISTEL project. We will show how a detailed experimental characterization and a detailed laser modeling have led to a better understanding of the laser behaviors with a particular attention to single mode laser emissions. The whole set of results opens new perspectives for photonic crystal lasers in the substrate approach.
