Thin Film Optical Waveguides in 2-5 Semiconductors
Abstract
A number of GaAs/GaAsP 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 dB/cm loss for a single mode waveguide, which is the lowest reported to date. Preliminary result on sandwiched GaAsP/GaAs/GaAsP gives a 6 dB/cm 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.
