Abstract

We have developed directly modulated membrane lasers on a high-thermal-conductivity SiC substrate, which exhibit bandwidth of >110 GHz at 25°C, and 74 GHz at 85°C by large relaxation oscillation frequency and optical feedback effect. We demonstrate 2-km transmission of 100-Gbit/s NRZ signals with uncooled operation.
