A non-blocking N&times;N cross-connect is provided that has an array of liquid crystal (LC) switches in a grid of planar optical waveguides within a light optical circuit (LOC). LC-filled trenches are used in a planar optical waveguide and each trench provides the functionality of a waveguide polarization splitter, a transverse electric (TE) switch cross-point, a transverse magnetic (TM) switch cross-point, or a waveguide polarization combiner. The planar optical waveguide has a refractive index substantially equal to the lowest index of refraction of the LC material. By combining these elements, a cross-connect system is fabricated. Also disclosed is a dynamically adjustable prism constructed with a liquid crystal material.
