Impact of temperature on optical properties of InGaAs/GaAsSb/InAlAs nano-scale heterostructure

The present article reports the impact of temperature on optical properties of InGaAs/GaAsSb/InAlAs nano-scale heterostructure which has been assumed to grow on GaAs substrate. For this heterostructure, the optical properties such as optical gain and transition wavelength have been simulated under the variable temperature with the help of 6 band k.p approach. The outcomes of the calculations inform that the increased temperature can reduce the optical gain appreciably with the red shift in wavelength in near infrared (NIR) region.
