Abstract
We demonstrate that the transverse eigenmodes in a waveguide that combines a parabolic index guide with a Gaussian gain guide can be highly nonorthogo nal. The excess-noise factor K that arises from this nonorthogonality exhib its resonant features with maximum values that can easily reach K approxima te to 400. This simple model applies directly to stable-cavity microchip la sers with focused gain. (C) 2001 Optical Society of America.
