Abstract

An optical waveguide switch has been realized utilizing the total reflection critical angle controlled by the motion of a dielectric chip set on a waveguide surface. By the contact–noncontact of a GGG chip with the SiO2–Ta2O5 waveguide film having a built-in low refractive-index channel, a switching angle of 22.5° and extincion ratio of 12–16 dB were obtained for the TE0 mode at 0.633-μm wavelength. A 1 × 3 switch that includes two switching positions driven by 6-V electromagnets is demonstrated.
