Paper Abstract

The lasing modes and the spontaneous emission factors of microdisk lasers are analyzed simply, in this paper, InGaAs/InGaAsP multiple quantum wells (MQW) microdisk lasers are fabricated by using the methods of active ion etching and selective chemical etching. The diameter of the microdisk lasers was 3 micrometers . InGaAs/InGaAsP MQW microdisk lasers was optically pumped when cooled with liquid nitrogen. We obtained the single-mode lasing at 1.5 micrometers wavelength, with threshold pump power 18 (mu) w.
