We describe directly modulated membrane lasers on high-Thermal-conductivity SiC exhibiting a 42-GHz fr and intrinsic 60-GHz bandwidth, thanks to the high optical confinement and low device thermal resistance. Utilizing a photon-photon resonance effect at 95 GHz, we demonstrate a 108-GHz bandwidth and 132-Gbit/s NRZ modulation.
