摘要： A non-blocking N×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.

摘要： A polyester having less than 50 hydrogen-carbon bonds per 1000 molecular weight units exhibits very low optical loss in the range of wavelengths commonly used for optical communication, and exhibits other physical properties suitable for use as a waveguide core material and/or a waveguide cladding material in optical fibers and/or planar optical devices.
