Abstract

본 발명은 제1다수의 도파관(waveguide) 및 제1다수의 도파관에 접속되는 제1자유 공간 영역(free space region)을 포함하는 광학 장치(optical apparatus)에 관한 것으로, 특히, 제2다수의 도파관이 제1자유 공간 영역에 접속되는 광학 장치에 관한 것이다. 광 회절격자(optical grating)는 제2다수의 도파관에 접속되며, 다수의 동일하지 않은 길이의 도파관을 포함한다. 제3다수의 도파관은 광 회절격자에 접속되며, 제2자유 공간 영역은 제3다수의 도파관에 접속된다. 적어도 하나의 도파관은 제2자유 공간 영역에 접속된다. 제1다수의 도파관은 제1자유 공간 영역으로부터 멀리 떨어진 단부(ends)를 갖는 적어도 두개의 인접 도파관을 포함한다.
Y-분기 커플러(Y-branch coupler)는 두개의 인접 도파관의 원격 단부(remote ends)에 접속된다. 인접 도파관은 명시할 수 있는 통과대역 폭(specifiable passband width)을 발생하기 위해 제1자유 공간 영역을 따라 떨어진 소정 거리로 위치된다.
