Hexagonal boron nitride (h-BN) has received a great deal of attention as a substrate material for high-performance graphene electronics because it has an atomically smooth surface, lattice constant ...

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 ...

In this work, the temporal fluctuations of lateral modes in high-power broad area semiconductor lasers are investigated in the time domain. Index guiding (in the form of etched holes) is introduced as ...
