Liverpool Keep Tabs as Newcastle Star Weighs Future Newcastle United are bracing for a significant test of resolve as one of their most valuable assets considers his next move. The forward, who was ...

We presented a technique to realize single-mode quantum cascade lasers by simply etching several large-period slots in the ridge, which leads to refractive index perturbations and mirror-loss spectrum ...

A numerical model for high-power diode lasers is employed to predict the lateral divergence angle over current for one emitter out of a laser array. The calculated values are compared to experimental ...
