Abstract

A L-band two-section AlGaInAs/InP asymmetric multiple quantum well (QW) passively mode-locked laser has been used to generate a frequency comb with a 100 GHz spacing at a central wavelength of 1610 nm. The comb contains 10 optical lines within a -3 bandwidth of 8.05 nm and 34 optical lines within a -20 bandwidth of 30 nm. The mode-locked pulse duration was 440 fs. To the best of our knowledge, this is the shortest pulse duration from any directly electrically pumped QW semiconductor mode-locked laser.

摘要

一个L波段两段式AlGaInAs/InP非对称多量子阱（QW）被动锁模激光器已被用于产生中心波长为1610nm、频率间隔为100GHz的频率梳。该频率梳在8.05nm的-3dB带宽内包含10条谱线，在30nm的-20dB带宽内包含34条谱线。锁模脉冲持续时间为440飞秒。据我们所知，这是任何直接电泵浦量子阱半导体锁模激光器产生的最短脉冲持续时间。
