Abstract

In this paper, a novel wavelength selectable multi-channel OADM(Optical Add/Drop Multiplexers) is proposed and experimentally demonstrated. The proposed OADM drops simultaneously more than one channel among many channels with small wavelength tuning by using one sampled grating and FBGs, Interchannel crosstalk (or interchannel rejection ratio) better than 20[dB] has been shown experimentally.

본 논문에서는 샘플격자를 이용한 새로운 파장가변형 다채널 OADM(Optical Add/Drop Multiplexers)을 제안하고 그 특성을 살펴보았다. 제안된 새로운 파장가변형 다채널 OADM은 한 개의 샘플격자와 한 개 이상의 FBG를 사용하여 격자의 작은 중심파장이동으로도 여러 개의 채널 중에서 한 개이상의 채널을 동시에 추출할 수 있으며, 이때 인접채널간의 제거비가 20[㏈]이상으로 인접채널간 crosstalk 특성이 매우 우수함을 알 수 있었다.
