Abstract

We present a method to implement a $M{\times}N$ switching system by use of an $M{\times}1$ multimode waveguide and N hologram filters. The pass of optical signals is provided by an $M{\times}1$ multimode waveguide. The complex speckle patterns generated from the multimode waveguide are recorded into the N hologram filters and used as the code for destination. The feasibility of our method is experimentally demonstrated.

$M{\times}1$의 다중모드 도파로와 N개의 홀로그램 필터를 이용하여 M개 입력단자와 N개 출력단자 사이에 광신호 교환을 수행할 수 있는 방법을 제안한다. 광신호 경로는 $M{\times}1$의 다중모드 도파로를 사용하고, 이것으로부터 발생하는 스페클 패턴들을 연결 목적지를 결정하는 목적코드로 이용한다. 제안한 시스템에 대해 광신호 교환이 가능함을 실험적으로 보였다.
