Abstract

Single-mode integrated optic waveguide demultiplexer structures were fabricated consisting of a 4-pm-wide input channel waveguide, an adiabatic beam expansion horn 130 μm at its output, a planar waveguide region, and several 3-μm period grating structures embedded in the planar waveguide region. The angular orientation of the gratings was adjusted to varying at specific wavelengths. The planar waveguide, the channel waveguide, the horn, and the grating structures were simultaneously formed by dilute silver nitrate ion exchange on an aluminum masked slide. High diffraction efficiencies were observed in good agreement with the theoretical model for the horn-grating interaction at 0.6328-, 0.789- and 0.82-μm wavelengths. This is the first reported operation of a single-mode demultiplexer structure with simultaneously fabricated input waveguide, beam expansion, and recollimation horms and multiple diffraction gratings.
