Abstract

The strain effects on the optical gain properties of wurtzite InGaAIN multiple quantum well blue laser diode structures were investigated using the sell-consistent method and the multi band Hamiltonian for the strained wurtzite crystal. 2% compressive strain gave up to 60% enhancement to the differential gain as well as 15nm blue shift in the lasing wavelength.
