Paper Abstract

The linewidth broadening of Distributed Feedback (DFB) semiconductor lasers under direct modulation become more and more serious with the increase of modulating data rate. So it is important to investigate externally modulated transmitter module whose dynamic linewidth is the same as its static linewidth. The integrated module including DFB-LD and LN modulator reported here has a 3 dB-bandwidth of 3.8 GHz, 4 V drive voltage, and operating wavelength at 1548 nm, its linewidth is about 100 MHz measured by Gated Delay Self Homodyne and output power is 200 (mu) W. It has been used in optical transmission system and shows good characteristics.
