Abstract
The distributed-feedback, surface-emitting laser diode with lateral double heterostructure (LDH) is realised with the combination of molecular beam epitaxy (MBE) and selective liquid-phase-epitaxial (LPE) techniques. Stimulated emission with a spectrum width of 2–3 nm was observed at the operating current of 100mA at −50°C, and 400 mA at room temperature.
