Abstract

In this paper we propose the simple system for measuring the chromatic dispersion of a fiber by using Sagnac interferometer with a Mach-Zehnder modulator and induce the equivalent model and the transfer function of this system. The chromatic dispersion of fibers with length of 2.235km is measured by using this method in wavelength region from 1500nm to 1580nm and we conform that the measured results had a good agreement with the theoretical results given Corning Fiber.

본 논문에서는 Mach-Zehnder 변조기가 포함된 Sagnac 간섭기를 이용한 간단한 색분산 측정 방식을 제안하고, 제한한 시스템의 등가모델과 등가 전달함수를 유도하였다. 색분산은 2.235km 길이의 광섬유의 이용하여 측정하였으며 이론적인 값과 1500nm에서 1580nm의 파장 범위에서 매우 잘 일치함을 확인하였다.
