High speed modulation characteristics of long wavelength vertical cavity lasers based on an integrated InP Bragg reflector

The high-speed performance of 1.55 /spl mu/m GaInAsP MQW vertical cavity lasers based on a 50-period GaInAsP-InP bottom mirror operating continuous-wave at low temperature is presented. The maximum small-signal modulation bandwidth was limited by parasitics to 3.4 GHz.
