An energy efficient 1060 nm GaAs‐based oxide‐confined vertical‐cavity surface‐emitting laser designed for high‐speed modulation and single‐mode emission has been developed. A record data rate of 50 Gbit/s at an energy dissipation of 100 fJ/bit is demonstrated for a device with >50 dB side‐mode‐suppression and 0.2 mA threshold current, making this laser a promising light source for long‐reach optical interconnects.
