G. Ungaro et al., ROOM-TEMPERATURE CONTINUOUS-WAVE OPERATION VCSEL AT 1.48-MU-M WITH SB-BASED BRAGG REFLECTOR, Electronics Letters, 34(14), 1998, pp. 1402-1404
The authors present, for the first time, room temperature CW operation
of an optically-pumped vertical cavity laser emitting at 1.48 mu m, i
ncorporating an Sb-based mirror on InP. The structure also includes st
rained AlGaInAs quantum wells and a wafer-fused AlGaAs mirror The inpu
t threshold power is 50mW at 20 degrees C and has a minimum value of 2
7 mW at 230K.
