Abstract
A semiconductor laser adapted for telecommunications applications. The opitical mode delivered by the laser has a high power output beam and a narrow far field, thus, enabling efficient coupling of the laser into small numerical aperture optical fibers. The laser is made up of a semiconductor heterostructure and one or more optical trap layers.
