Abstract : The objectives of this program were: To analyze the index of refraction of various regions of lasers as a function of the aluminum concentration in (AlGa)As so that lasers can be synthesized with optimum radiation patterns in the sense that the power beamwidth will be minimized; to produce design curves showing the beamwidth for various laser structures; and, to investigate laser structures which produce waveguide modes giving the smallest possible radiation pattern divergence.
