Abstract

We generate 10 GHz short pulses from a continuous wave laser at 1.5 um by cascaded intensity and phase modulation, followed by chirp compensation using a single mode fiber. The measured spectral and pulse widths are 0.64 nm and 5.7 ps respectively, resulting in the time-bandwidth product of 0.46.

광 강도 및 위상변조 후에 단일 모드 광섬유로 첩을 보상함으로서 CW 광원으로부터 10 GHz 초단 펄스를 발생시켰다. 발생된 펄스는 0.64 nm의 스펙트럼 폭과 5.7 ps의 펄스폭을 보임으로서 시간대역 곱이 0.46인 준 변환제한된 펄스임을 보였다.
