high as 14% have been achieved from a single facet, which to our knowledge, is the highest reported value for any CW room-temperature injection laser. The high-power low-threshold devices are constructed by minimizing the lateral current spread, using short (150 pm) cavities, and applying a novel dielectric-stack facet reflector with nearly 100%(More)
We have developed a unique approach for evaluating the local composition x as a function of position on the surface of crystals of Hg(1-x) Cd(x) Te utilizing electrolyte electroreflectance. The method is nondestructive and can be employed at room temperature. The technique is sensitive enough to determine changes of composition Deltax approximately 0.002(More)
