First Room Temperature CW Operation of GaInAsP/InP Surface Emitting Laser

Abstract
We have achieved the room temperature cw lasing operation in GaInAsP/InP vertical cavity surface emitting laser diodes for the first time. By employing a buried heterostructure with a 1.3 μm range circular active region1 and a thermally conductive MgO/Si heat sink mirror, the cw lasing operation was obtained up to 14 °C, as shown in Fig. 1.
