Abstract

A novel linearization method of a DFB-LD using the dual-parallel scheme is proposed. This scheme consists of two DFB-LDs with different wavelengths and an optical combiner. By controlling only the bias current of LDs, the intermodulation distortion can be suppressed. IMD3 suppression of more than 15 dB was experimentally obtained.

DFB-LD双并行模拟调制中的非线性失真抑制

提出了一种新的双并行DFB-LD线性化方法。该方案由两个不同波长的dfb - ld和一个光合成器组成。通过仅控制ld的偏置电流，可以抑制互调失真。实验获得了超过15 dB的IMD3抑制。
