초록
모드잠금 고리형 광섬유 레이저 출력의 단열 쏠리톤 펄스압축에 의해 1545 ～ 1550 nm 파장영역에서 400 ??토초의 안정성이 뛰어난 변환제한급의 10 GHz의 광 펄스를 발생시켰다. 특별한 슈퍼모드 선택소자를 사용하지 않고도 -123 dB/Hz 이하의 슈퍼모드 비팅 잡음 억제에 의해 1 kHz ～ 100 MHz의 잡음대역에서 100 ??토초 미만의 낮은 시간 지터를 얻었다.
Abstract
We report 400 femto-second highly stable, nearly transform-limited, pulse generation at 10 GHz in 1540 ～ 1550 nm wavelength region by adiabatic soliton pulse compression of an actively mode-locked fiber ring laser output. Without using any supermode selection device, supermode beating noise has been suppressed below -123 dB/Hz, resulting less than 100 femto-second timing jitters at the noise band of 1 kHz ～ 100 MHz.
