Abstract

We have studied superluminescent diodes with simplified design and active region based on 5 or 7 layers of InGaAs/GaAs quantum well-dots (QWDs). Emission peaks of the individual QWD layers are shifted with respect to each other by 15–35 nm to provide as wide as possible emission line in a superluminescent mode with central wavelength of about 1 μm without significant spectral dips. For superluminescent diodes with the active region based on 5 and 7 QWD layers, the maximal value of full width at half maximum of emission spectrum was 92 and 103 nm respectively.

基于多个 InGaAs/GaAs 量子阱点层的宽带超发光二极管

摘要我们研究了基于 5 层或 7 层 InGaAs/GaAs 量子井点 (QWD) 的超发光二极管，其设计和有源区均已简化。各层 QWD 的发射峰相互偏移了 15-35 nm，以便在中心波长约为 1 μm 的超发光模式下提供尽可能宽的发射线，而不会出现明显的光谱衰减。对于活性区基于 5 层和 7 层 QWD 的超发光二极管，发射光谱半最大全宽的最大值分别为 92 纳米和 103 纳米。
