Abstract

The basic advantage of using multiple quantum wells (MQWs) in a laser system is that the threshold current density is reduced relative to conventional lasers due to the increased carrier density in MQWs and the associated increase in the optical gain due to the huge confinement factor. The temperature sensitivity of this gain is also reduced compared to bulk material so that the MQWs-based laser can be designed to operate efficiently at room temperature much higher than conventional semiconductor lasers.
