Abstract

We present a directly modulated membrane laser on high-thermal-conductivity SiC exhibiting >100-GHz bandwidth. A ~40-GHz relaxation oscillation frequency, owing to low thermal resistance and high optical confinement, and a ~95-GHz photon-photon resonance are achieved. Net 239.3-Gbit/s PAM-4 transmission over 2-km standard single-mode fibre is demonstrated.
