Paper Abstract

The advance of nanofabrication techniques allow us to realize microcavity lasers with an optical wavelength-size in one or three dimensions. In this work, the effect of microcavity to the optical pumping threshold is studied by using a simple two-level model. It is concluded that there are two factors that decrease the threshold of lasers, one is the transparency pump rate and the other is the additional pump rate while the latter is proportional to the reverse of (beta) , the spontaneous emission-coupling factor. InGaAs/InGaAsP/InP MQW microdisk lasers are fabricated by using nanofabrication techniques. The threshold pump power are 15 (mu) W and 170 (mu) W for disks with the diameter of 5 micrometers and 10 micrometers , respectively.
