Abstract :
The temperature-dependent effects in a segmented travelling-wave electroabsorption modulator are demonstrated and analysed. Optimum operation voltages with the highest modulation efficiency at different temperatures are identified. This can ensure the modulator working at 50 Gbit/s with RF extinction ratio >8.4 dB between 10-50/spl deg/C at /spl lambda/=1540 nm.
