Abstract

We propose and demonstrate a technique to increase the output power of a DFB laser transmitter from 6 mW to 16 mW, while still keeping the resultant composite second orders (CSOs) and composite triple beats (CTBs) meet standard CATV system requirements. This technique is based on a novel pre- distortion circuit, which can suppress laser's bias- dependent CSOs and CTBs significantly. The operation principle of this pre-distortion circuit is presented in this paper.
