Abstract:
We have measured the gain spectrum of an optically pumped 40A ZnCdSe-ZnSe multiple quantum
well. Our calculation, which includes many body effects such as Coulomb enhancement and spectral
broadening due to carrier scattering, gives excellent agreement with the experimental gain
measurements. We then show the importance of the inclusion of the Coulomb enhancement for the
calculation of optical gain when predicting laser threshold currents. This is emphasised by using our
gain calculation as a basis to theoretically optimise a simple ZnCdSe-ZnSe quantum well laser
structure incorporating the leakage current over the p-type cladding.
