摘要

本文报道了一种基于非对称多量子阱结构的被动锁模AlGaInAs/InP激光二极管，设计用于在$1.5~\mu $ m附近产生100 GHz光频梳。通过使用不同厚度但相同的材料成分，有源区域由两个不同光致发光波长的量子阱组成，优化了光谱重叠和拓宽模态增益曲线。该器件提供10.14 nm的- 3 dB光带宽，跨越14条线，间距为0.78 nm。据我们所知，这是直接电抽运量子阱被动锁模激光二极管中报道的最宽带宽。这些结果证明了一种紧凑实用的方法，可以利用非对称多量子阱锁模激光二极管产生宽带光学频率梳。

Broadband 100 GHz Frequency Comb From an Asymmetric MQW Passively Mode-Locked Laser

We report a passively mode-locked AlGaInAs/InP laser diode based on an asymmetric multiple quantum well structure, designed for 100 GHz optical frequency comb generation near

$1.5~\mu $

m. The active region comprises quantum wells with two different photoluminescence wavelengths by using different thicknesses but identical material composition, optimized to enhance spectral overlap and broaden the modal gain profile. The device delivers a −3 dB optical bandwidth of 10.14 nm, spanning 14 lines with a spacing of 0.78 nm. To the best of our knowledge, this is the widest bandwidth reported from any directly electrically pumped quantum-well passively mode-locked laser diode. These results demonstrate a compact and practical approach to generating wideband optical frequency combs using asymmetric multiple quantum well mode-locked laser diodes.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
