摘要

提出了一种用于FMCW激光雷达系统的两段DFB激光器。在200 kHz调制速率下，下匝道和上匝道的频率非线性分别为0.185%和2.88%，响应时间小于100 ns。

A high-linearity and fast-response direct-modulated DFB laser for low-cost FMCW Lidar

We proposed a two-section DFB laser for the FMCW lidar system. The measured frequency nonlinearity of down-ramp and up-ramp at 200 kHz modulation rate was 0.185 % and 2.88 %, the response time was below 100 ns.
