Abstract

The performance analysis of optoelectronic oscillator(OEO) based on a directly modulated semiconductor laser was theoretically achieved. First, the analysis was performed on the open response of the key components that constitute the OEO loop. Using the results, we simulated the open-loop characteristics of the OEO loop. By combining oscillation conditions of loop oscillator in addition to the open-loop magnitude and phase responses, theoretical performance analysis such as OEO's oscillation frequency, spurious tones and phase noise was successfully completed.

본 논문에서는 반도체 레이저의 직접 변조를 이용한 광전 발진기의 성능에 대한 이론적인 해석을 수행하였다. 먼저 광전 발진기를 구성 하는 각 부분의 응답 특성을 해석 하고, 이를 이용하여 광전 발진기 전체의 개방 루프 응답 특성을 얻었다. 다음으로 개방 루프 응답 특성의 크기 응답과 위상 응답 해석 결과에 루프 발진기의 발진 원리를 적용하여 광전 발진기의 발진 주파수, 스퓨리어스 톤의 간격, 위상 잡음의 성능을 도출하였다.
