Abstract
We report membrane lasers on high-thermal-conductivity SiC exhibiting flat small-signal responses with 3-dB bandwidths of 98 and 84 GHz at 25 and $55^{\circ}\mathrm{C}$, respectively, due to the high relaxation oscillation frequency and photon-photon resonance frequency. The laser is capable of semi-cooled 128-Gbit/s NRZ transmission.
