Title (EN) INTEGRATED MEMS SWITCHES FOR SELECTIVELY COUPLING LIGHT IN AND OUT OF A WAVEGUIDE
(FR) COMMUTATEURS MEMS INTÉGRÉS POUR COUPLER SÉLECTIVEMENT DE LA LUMIÈRE DANS ET HORS D'UN GUIDE D'ONDE
Abstract:
(EN) A steerable optical transmit and receive terminal includes a MEMS-based Nxl optical switching network. Each optical switch (322 - 336) in the switching network uses an electrostatic MEMS structure to selectively position a translatable optical grating (502) close to or far from an optical waveguide (510). In the close ("ON") position, light couples between the translatable optical grating (502) and the optical waveguide (510), whereas in the far ("OFF") position, no appreciable light couples between the translatable optical grating (502) and the optical waveguide (510). The translatable optical grating (502) is disposed at or near a surface of the optical switching network. Thus, the translatable optical grating (502) emits light into, or receives light from, free space. The steerable optical transmit and receive terminal also includes a lens (102) and can steer a free space optical beam in a direction determined by which port of the Nxl optical switching network is ON.
(FR) Un terminal d’émission et de réception optique orientable comprend un réseau de commutation optique Nxl à base de MEMS. Chaque commutateur optique (322 - 336) dans le réseau de commutation utilise une structure MEMS électrostatique pour positionner sélectivement un réseau optique translatable (502) à proximité ou loin d'un guide d'onde optique (510). Dans la position fermée ("ON"), la lumière se couple entre le réseau optique translatable (502) et le guide d'onde optique (510), tandis que dans la position éloignée ("arrêt"), aucune lumière appréciable ne se couple entre le réseau optique translatable (502) et le guide d'onde optique (510). Le réseau optique translatable (502) est disposé au niveau ou à proximité d'une surface du réseau de commutation optique. Ainsi, le réseau optique translatable (502) émet de la lumière dans l'espace libre ou en reçoit dudit espace. Le terminal d'émission et de réception optique orientable comprend également une lentille (102) et peut diriger un faisceau optique d'espace libre dans une direction déterminée par laquelle un port du réseau de commutation optique Nxl est activé.
