Paper Abstract

We review recent progress at Nortel Technology on the monolithic integration of a truncated-well 1 .55 im gain-coupled DFB with a Mach-Zehnder (MZ) modulator. Integrated MZ designs for both positive and negative chirp are described and analyzed. Link tests at 10 Gbit/s over 80 km ofnon-dispersion-shifted fiber (NDSF) show a negative dispersion penalty of 1 .1 dB, and steep BER curves with no evidence of flooring. The receiver sensitivity is found to be independent of pattern length, and independent ofthe laser operating wavelength, indicating negligible thermal, optical, and electrical crosstalk. Keywords: Integration, Mach-Zehnder, Gain-Coupling
