Abstract

A compact 10-Gb/s optical transmitter module with small-chirp output was developed by using a monolithically integrated electroabsorption modulator with a distributed-feedback laser. This module can be operated at a bit rate of more than 10 Gb/s at 1.55 mu m, and shows a high modulated output power of approximately 1 dBm with a low optical coupling loss of 3.2 dB between chip and fiber. A multifunctional and compact optical isolator with a monitor photodiode was also developed to decrease noise.<>
