Abstract

A new wavelength demultiplexing scheme using holographic volume phase grating formed in photopolymer is proposed and demonstrated. Through the analysis and experiments of the design parameters such as wavelength selectivity, operating spectral range, spatial channel distance and spatial intensity distribution of each channel, we proved that the proposed demultiplexing scheme is promising for wavelength division multiplexing (WDM). From the experimental results, the 3 dB bandwidth of 0.21nm and the crosstalk level of 26 dB for a 0.8 nm channel spacing are observed.

포토폴리머에 형성된 홀로그래픽 부피 위상 격자를 이용한 새로운 구조의 파장 역다중화기를 제안하고, 입증하였다. WDM 용 역다중화 소자로의 적용을 위해 격자의 파장선택성, 공간적 채널 거리, 채널 대역폭에 대한 이론적, 실험적 분석을 통해응용 가능성을 증명하였다. 실험결과 각 채널의 대역폭은 0.21 m이고, 채널간격이 0.8 nm일때 채널누화특성은 26 dB였다.
