Title:
導波管の内部および外部に光を選択的に結合するための統合MEMSスイッチ
Document Type and Number:
Japanese Patent JP7133552
Kind Code:
B2
Abstract:
An all-solid state optical transmit/receive terminal includes binary optical switches to steer an optical beam, without mechanical components, phased array of emitters/collectors or large number of phase shifters. A lens optically couples a surface array of emitters/collectors to free space, giving each emitter/collector a respective direction in free space. The emitters/collectors are also coupled, via an “H-tree” or other branched optical waveguide network, to a common input/output port, and from there to a receiver and/or transmitter. The binary optical switches are disposed at optical junctions of the optical waveguide network. ON switches pass an optical signal through the optical waveguide network, between the common input/output port and one or more selected emitter/collectors, thereby selecting a free space direction(s). Only a relatively small subset of the binary optical switches needs to be ON, therefore powered, simultaneously at any given time.
