Analysis of coupling efficiency between semiconductor lasers and rectangular dielectric waveguides
Abstract
The objective of this task was coupling from (rectangular) semiconductor laser sources to a rectangular optical waveguide. As a first step, a numerical calculation of coupling efficiency was programmed for the CDC-6400 computer at the University of Washington. This report summarizes the operation and results of the program. For examples run to date, this analysis indicates that neglecting Fresnel reflection coefficient losses at the fiber and coupling efficiencies that exceed 95% can be obtained in virtually all cases.
