摘要

实验研究了单片光注入锁定分布反馈(DFB)激光器的动态性能和对非线性畸变的抑制。主激光器和从激光器单片集成在一条强耦合DFB激光器中。光注入锁定是通过电流调谐实现的。该激光器的谐振频率由11ghz提高到23ghz，非线性失真被抑制了15db以上。

Modulation bandwidth enhancement and nonlinear distortion suppression in directly modulated monolithic injection-locked DFB lasers

We have experimentally investigated the dynamic performance and the suppression of nonlinear distortions of a monolithic optical injection-locked distributed feedback (DFB) laser. The master and the slave lasers are monolithically integrated in a single strip of strongly coupled DFB laser. Optical injection locking is achieved by current tuning. The resonant frequency of the laser is increased from 11 GHz to 23 GHz, and nonlinear distortions are suppressed by more than 15 dB.
