Abstract :
InGaAsP microdisk lasers are fabricated on Al/sub x/O/sub y/ by wafer fusion. Room-temperature continuous-wave operation with threshold pump power of 1.13 mW has been achieved from a 2.2-μm diameter microdisk laser. The lasing wavelength with incident pump power redshifts at a rate of 0.28 nm/mW which shows the improved thermal characteristics due to the high thermal conductivity of Al/sub x/O/sub y/ bottom layer.
