  • Optically induced refractive index modification in ferroelectric optical
    Publication number: 20060104568
    Abstract: A method of inducing refractive index modifications in ferroelectric materials through the application of light in the form of scanned or patterned irradiation, removing the light to leave a permanent refractive index modified structure. This method can be used to design and engineer surface or near-surface structures in the form of waveguides, junctions, splitters and couplers, for application in optical circuitry, integrated optics, and active waveguide devices.
