Asymmetric multiple-quantum-well heterostructures: conception, properties, and laser characteristics

The modeling simulation of the asymmetric MQW heterostructure laser performance allows one to chose the active region parameters for required regimes of the operation, such as bistable switching and regular pulsation at several remote wavelengths. In accordance with the structure design and pump conditions, both the spectral and output power characteristics of these laser systems can be easily changed. Use of the asymetric MQW heterostructures gives new opportunities to extend gain spectra and is essential to weaken its sensitivity to polarization.
