ABSTRACT:
In order to reduce the possibility of a laser operating in multiple transverse modes at high power, the laser is provided with laterally asymmetric losses that discriminate against modes higher than the fundamental mode. One approach to doing this is form an asymmetric ridge waveguide in the laser, that allows the light of the higher order modes to leak out of the waveguide.
