The effect of strain on the band structure of In/sub x/Ga/sub 1-x/P-In/sub 0.5/Al/sub 0.5/P multiple quantum wells (MQW's) has been investigated from high-pressure and low-temperature photoluminescence measurements. The biaxial strain in the wells wa

The output power of an external-cavity-tuned laser has been significantly increased by using an output coupler with a wavelength-dependent reflectivity. Our algorithm for determining the optimum wavelength dependence uses a simple gain model, and all
