Abstract

We demonstrate a thermally stable, high-power InAs/GaAs quantum dot (QD) four-channel distributed feedback (DFB) laser array featuring an ultra-narrow linewidth and low noise. Each channel of the array delivers a continuous-wave output power exceeding 34 mW and 17 mW at

$25~^{\circ }$

C and

$85~^{\circ }$

C, respectively, with side-mode suppression ratios >45 dB. Furthermore, the device exhibits an ultra-narrow linewidth as low as 1.60 kHz and low relative intensity noise (RIN), with peak RIN values below −165 dB/Hz at

$50~^{\circ }$

C. These results demonstrate the potential of QD DFB laser arrays for energy-efficient and cost-effective wavelength-division multiplexing data transmission systems in uncooled operation scenarios.

热稳定高功率1.3 μm InAs/GaAs量子点分布式反馈激光阵列

我们展示了一种热稳定，高功率InAs/GaAs量子点（QD）四通道分布式反馈（DFB）激光阵列，具有超窄线宽和低噪声。阵列的每个通道在$25~^{\circ}$ C和$85~^{\circ}$ C下分别提供超过34 mW和17 mW的连续波输出功率，侧模抑制比>为45 dB。此外，该器件具有低至1.60 kHz的超窄线宽和低相对强度噪声（RIN），在$50~^{\circ}$ c时，峰值RIN值低于- 165 dB/Hz。这些结果表明，QD DFB激光阵列在非冷却操作场景下具有节能和经济效益的波分复用数据传输系统的潜力。

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.
