Abstract

An optical switch (218) is integrated into a planar waveguide substrate in order to selectively switch light (240, 301, 351) entering the switch from one waveguide (232, 234) to exit the switch along either of at least two other waveguides (236, 238). The optical switch (218) includes an electro-optic material (222), preferably PLTZ, that is deposited into a cavity (220) formed within the substrate (214). The switch (218) includes first and second regions (226, 228) that interface at a boundary (230), and the electro-optic material (222) is located in one of the regions (226, 228) such that an electrical field source (212, 213, 224) coupled to the material (222) in the one region (226) adjusts the boundary (230) between transmission and reflection modes. PLTZ is provided in the switch (11) in a formulation that provides little hysteresis with respect to the applied field, and in particular is a non-ferroelectric, cubic, relaxor, polycrystalline, ceramic type having a lanthanum concentration of between about 8.5% and about 9.0%.
