Single-mode Lasing of Microdisk Lasers with Low Threshold
The lasing modes and the spanteneous emission factors of microdisk lasers are simply analysized in this paper. InGaAs/InGaAsP multiple quantum wells (MQWs) microdisk lasers are fabricated by using the methods of active ion etching (RIE) and selective chemical etching. The diameter of the microdisk lasers was 3 μm. InGaAs/InGaAsP MQWs microdisk lasers cooled by liquid nitrogen was optically pumped. The single mode lasing at 1.506 μm wavelength with threshold pump power about 18 μW is obtained.
