Title:
光通信システム、光受信機、及び光受信機における調整方法
Document Type and Number:
Japanese Patent JP6407101
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an optical communication system, an optical receiver and an optical receiver adjustment method, capable of stably transmitting a large amount of data at high speed through optical transmission using a plurality of optical transmission channels.SOLUTION: The optical communication system includes: an optical transmitter 101 which transmits a plurality of signal beams in parallel; and an optical receiver 201 which receives a plurality of signal beams in parallel. The optical receiver 201 includes: a photodetector unit 210 having a photodetector element group 212 which receives a plurality of signal beams from a plurality of photodetector elements 211 disposed in an array shape; an optical mechanism 220 including a mechanism for forming an image group 312, composed of a plurality of images 311 of the signal beams on the photodetector unit 210, and for variably magnifying the size of the image group, and a mechanism for moving the image group position on the photodetector unit; and a control unit 280 which controls the operation of the optical mechanism 220 on the basis of a detection signal output from each of the plurality of photodetector elements 211, in such a manner that the plurality of signal beams are respectively incident on the plurality of photodetector units 211.SELECTED DRAWING: Figure 1
