在这项工作中，讨论了使用两个相同的QD soa来提高扫描激光系统在OCT应用中的性能，从而使带宽增加到94nm。介绍了基于GaAs的QD soa和基于InP的QW soa相结合实现OCT系统宽带源的方法。扫描激光源在1193nm ~ 1347nm范围内的光谱带宽为154nm，平均功率为8mW，滤波ASE源的带宽为225 nm。
In this work the use of two identical QD SOAs to enhance the performance of swept laser system for OCT applications is discussed, resulting in an increase in bandwidth up to 94nm. The combination of GaAs based QD SOAs and InP based QW SOAs for realizing broad bandwidth sources for OCT system is described. For the swept laser source a 154nm spectral bandwidth from 1193nm to 1347nm and an average power of 8mW is obtained and for the filtered ASE source a 225 nm bandwidth is demonstrated.
