Self Consistency

Fundamental optical properties of strained wurtzite GaN quantum-well laser are calculated and evaluated near the threshold condition. The formalism is based on a self-consistent methodology that couples an envelope-function Hamiltonian for band structures with photon-carrier rate equations. Details of energy band structure, optical gain, and modulation response are studied comprehensively under the effects of strain-induced piezoelectric fields, bandgap renormalization, and the carrier capture processes. Comparisons between different approximations show that self-consistency is essential to accurately simulate pseudomorphically strained wurtzite GaN quantum-well lasers.
