Abstract

This paper presents a transmissive dispersion compensator based on tilted chirped fiber Bragg grating pairs which happen mode coupling between core mode and cladding mode. And, as a result of simulation, the phase matching condition and optimum tilted angle to maximize the mode-coupling in the dispersion compensator are shown and the dispersion slope and bandwidth in the proposed dispersion compensator is respectively 3,068ps/nm and 0.45nm.

본 논문에서는 서로 반대방향으로 진행하는 코어모드와 클래딩모드사이에서 모드결합이 일어나는 경사진 선형처프된 광섬유격자쌍을 이용한 새로운 투과형 분산보상기을 제안하였다. 제안된 투과형 분산보상기에서 모드결합이 최대로 일어나기 위한 위상정합조건과 최적의 경사각을 제시하였으며, 시뮬레이션을 통해서 제안된 투과형 분산보상기의 분산기울기와 분산보상 가능한 대역폭은 각각 3,068ps/nm와 0.45nm이고, 투과형 분산보상기로 동작함을 보여주었다.
