Abstract :
A systematic study of changing the reflectivity of a Si/SiO/sub 2/ mirror for 1.3- mu m GaInAsP/InP surface-emitting lasers is discussed. An effective threshold current of 4.5 mA at 77 K continuous operation has been obtained. This indicates a possibility of a submilliampere threshold at 77 K and approximately=20 mA at 300 K by optimizing the mirror reflectivity.<>
