- Abstract
- Wavelength conversion is demonstrated for the first time at 10 Gb/s in a Mach-Zehnder interferometric wavelength converter monolithically integrated with a CW probe source of a loss-coupled distributed feedback (DFB) laser diode. The integrated device was fabricated using a buried ridge stripe (BRS) structure with an undoped InP clad layer on the top of a passive waveguide to reduce high propagation loss. Good performance at lOGb/s was obtained with an extinction ratio of 7dB and a power penalty of 2.8 dB at a 10-9 bit error rate.
