摘要

利用二次谐波产生的频率分辨光门控(SHG-FROG)研究了基于InAs/InP量子破折号的单节fabry - p激光器的锁模特性。该器件利用优化的外延结构，模态增益为50 cm-1，显示出宽度超过14 nm的宽而平坦的发射光谱。采用单模光纤(SMF)进行腔内色散补偿后，可观察到宽度低至430fs的自启动脉冲。

Frequency-resolved optical gating measurements of sub-ps pulses from InAs/InP quantum dash based mode-locked lasers

Mode-locking of single-section Fabry-Pérot lasers based on InAs/InP quantum dashes is studied by second-harmonic generation frequency-resolved optical gating (SHG-FROG). The devices take advantage of an optimized epitaxial structure with modal gain of 50 cm-1 showing a broad and flat emission spectrum of width in excess of 14 nm. Self-starting pulses of a width down to 430 fs are observed after intracavity dispersion compensation using single-mode fiber (SMF).
