Experimental Study and Simulation of the Spectral Characteristics of LED Heterostructures with an InAs Active Region

The spectral parameters of midinfrared LED heterostructures with an InAs active region were studied experimentally, calculated using MATLAB, and simulated in COMSOL Multiphysics. The obtained data were compared to reveal the mechanism of formation of the emission spectra of these heterostructures. The results confirm that simulation is a promising design tool for LED structures.
