Patent

CA 2474330

A photonic light circuit device is described that comprises a semiconductor substrate (220) and two or more optical components (226, 228, 236, 240) wherein one or more hollow core optical waveguides (230, 232, 224) are formed in the semiconductor substrate to optically link said two or more optical components. The PLC may comprise a lid portion (44) and a base portion (42). The PLC can be adapted to receive optical components (8;608) or optical components may be formed monolithically therein. Coating with a reflective layer is also described.

L'invention a trait à un dispositif à circuit d'éclairage photonique (PLC), comprenant un substrat à semi-conducteur (220) et au moins deux composants optiques (226, 228, 236, 240), un ou plusieurs guides d'ondes optiques à noyau creux (230, 232, 224) étant formés dans le substrat à semi-conducteur afin de relier par voie optique lesdits composants optiques. Le PLC peut comprendre une partie couvercle (44) et une partie base (42). Le PLC peut être adapté de manière à recevoir des composants optiques (8, 608), ou des composants optiques peuvent y être formés de manière monolithique. L'invention concerne également un revêtement consistant en une couche réflectrice.
