Abstract

We report on the parameter-dependent optical characteristics of the unidirectional single-mode lasing square ring cavities. Using the taper-step section in the square cavities, the resonant direction can be selected and we characterize the optical losses by changing the taper lengths. Various kinds of square ring cavities are fabricated, based on InGaAsP/InGaAs multiple quantum well semiconductor materials. From the experimental results we obtain the optimized taper length for a given device structure, while maintaining unidirectional single-mode lasing.

본 연구에서는 단일모드 사각형 링 공진기에 테이퍼-스텝 구조를 적용하여 단 방향 발진을 구현하였으며, 다양한 테이퍼-스텝 구조 변수를 갖는 소자를 제작하여 그 특성을 분석하였다. 소자는 InP기판을 기반으로 성장된 InGaAsP/InGaAs 다중 양자 우물구조의 반도체에 제작하였으며, 제작된 소자의 출력과 광 손실을 측정하였다. 이를 바탕으로 주어진 반도체 에피 구조와 단일모드 사각 링 공진기에서의 최적화된 구조 변수를 도출할 수 있었다.
