Microdisk lasers with three InGaAs/InAlGaAs quantum wells were demonstrated for the first time. The selective etching method to fabricate the InGaAs/InAlGaAs microdisk laser structure is discussed. The lasers with 20 μm in diameter lase with single mode at 1.5-μm wavelength when optically pumped with pulsed Argon-ion laser at 80 K.
