Abstract :
A room-temperature continuous-wave operation of a 1.3 μm wavelength transistor laser (TL) with p/n/p configuration was achieved using AlGaInAs/InP 5 quantum-well active region A threshold current (emitter current) of 17 mA was obtained for a stripe width of 1.8 μm and a cavity length of 500 μm, and it was controlled by the collector-base voltage. Even though the current gain was only 0.01, three terminal operation was demonstrated and it can be improved by introducing n/p/n-TLs.
