Near room-temperature continuous-wave operation of electrically pumped 1.55 ÎŒm vertical cavity lasers with InGaAsP/InP bottom mirror

• The first near room-temperature continuous-wave (CW) operation of a vertical cavity laser based on an epitaxial InGaAsP/InP bottom mirror is reported. The structure employs a package of nine strain compensated GaInAsP quantum wells and a wafer-fused GaAs/AlGaAs top mirror. For a 10 ÎŒm diameter device, the threshold current is 6mA and the input threshold power is 21mW. The maximum operating temperature is 17 and 101°C for CW and pulsed conditions, respectively. © IEE 1999.
