A significant enhancement of the brightness is predicted in tapered lasers with the active layer asymmetrically located in the optical cavity. The balance between the reduced tendency to beam filamentation, the increase of threshold current, and the

A two-dimensional self-consistent laser model has been used for the simulation of the facet heating of red emitting AlGaInP lasers. It solves in the steady-state the complete semiconductor optoelectronic and thermal equations in the epitaxial and lon

Publikováno v: SPIE Proceedings.

High-brightness diode lasers at 1060 nm are useful in display applications (to provide green light by frequency doubling) and in free-space optical communications. On Al-free active region laser structures, we have obtained low optical losses of 0.9
