Abstract

By using an equivalent network based on Floquet's theorem and bisection principle, the optical properties of planar DFB guiding structure are evaluated. The optical parameters, such as Bragg condition and the reflectivity as a function of grating period, are numerically calculated. The numerical results reveal that this method offers a simple and convenient algorithm to analyze the optical characteristics of DFB configurations.

Floquet의 정리와 이등분의 원리 (bisection principle)에 기초한 등가 전송선로 해석법을 이용하여 평면 DFB 구조의 반사특성을 해석하고, 격자주기 (grating petiod)에 따른 분산특성과 전력반사도를 계산하였다. 수치해석 결과 등가 전송선로 해석법은 DFB 전송구조의 광학적 특성을 분석하기 위한 간편하고 유용한 알고리즘으로 사용될 수 있음을 보여 주었다.
