Étude en champ proche optique de cristaux photoniques bidimensionnels sur membrane suspendue

Nous presentons une etude experimentale en champ proche optique d'un cristal photonique 2D inscrit dans une membrane suspendue photoluminescente emettant a 1.5 μm. Les images obtenues mettent en evidence le guidage de la PL par la membrane, l'effet de bande interdite photonique ainsi que l'inhibition de l'emission de PL a l'interieur du cristal photonique.

Near-field probing of active photonic-crystal structures

We report a study of the optical near field of an active integrated component operating near the 1.55-mum telecommunications wavelength. The device is based on a two-dimensional photonic crystal etched in a suspended InP membrane. Topographic as well as optical information is collected by use of a scanning near-field optical microscope in collection mode, providing information about the local distribution of the losses.
