摘要

在可调谐DFB激光阵列(TLA)中，我们研究了400 ghz宽度的高速高可靠性波长切换，这是单束DFB激光器的最大调谐范围。通过提高电流/温度协同反馈控制的精度，我们实现了130 ms的高速波长切换时间和52 mA的低注入电流。

Experimental Demonstration of Full-Range High-Speed High-Reliability Wavelength Switching at DFB Laser with Current/Temperature Cooperative Control

We studied a high-speed high-reliability wavelength switching at 400-GHz width, which is the maximum tuning range of a single DFB laser in the tunable DFB laser array (TLA). By improving the accuracy of current/temperature cooperative feedback control, we achieved a high-speed wavelength switching time of 130 ms as well as a low injection current of 52 mA.
