Abstract

To realize a desired characteristics of an optical transversal fitters, The number of optical amplifiers as same as the lentgh of a given transfer function is needed In this paper, we consider an optical transversal filter that uses only one fiber amplifier, which can realize a constant(=$\alpha$) times of a given transfer function with e as large as possible in order to make use of optical signal energy. We also present some applications using this optical fiber filter.

광트랜스버셜 필터를 이용하여 희망하는 특성을 실현하기 위해서는 주어진 전달함수의 차수 만큼의 광섬유 증폭기를 사용하여야 한다. 본 논문에서는 단지 한 개의 광섬유 증폭기를 이용하여 주어진 전달함수의 정수 배를 실현할 수 있는 광트랜스버셜 필터에 대하여 논한다. 이때 광신호 에너지를 유효하게 사용하기 위하여 광신호 에너지를 최소로 하는 설계법을 적용하였다. 그리고 제안한 광트랜스버셜 필터를 이용한 몇 가지의 응용에 대하여 논하였다.
