Modeling of optical gain in GaInNAs quantum wells by using 8-band and 10-band models

摘要

We analyzed two approaches to calculate band structure and optical gain in GaInNAs/GaAs quantum well structures based on 10-band and 8-band kp models. The obtained results are discussed in the context of importance of conduction band nonparabolicity. We also briefly report on the influence of hydrostatic pressure on optical gain in this system.
