Abstract:

A number of GaAsGaAsP waveguides have been grown on wafers with maximum dimensions on the order of 7 cm. The surface alloy composition variation is within less than 1. Waveguide attenuation measurement at 10.6 micrometers gives a 2 dBcm loss for a single mode waveguide, which is the lowest reported to date. Preliminary result on sandwiched GaAsPGaAsGaAsP gives a 6 dBcm loss for a single mode waveguide. Waveguide work at one micrometer wavelength has been initiated. Light couplings through edge illumination, grating coupler, and prism coupler are successful.
