  • Closed-loop control of tunable optical wavelength filters
    Patent number: 6728445
    Abstract: A wavelength selective optical device for locking to a selected wavelength in an ITU grid includes a first waveguide, a second waveguide, a heating element and a control unit. The first waveguide includes a tunable filter formed in the first waveguide and the second waveguide includes a reference filter formed in the second waveguide. The heating element is in thermal contact with the tunable filter and the reference filter and the control unit is coupled to the heating element and the reference filter. The control unit varies a temperature of the heating element responsive to an indication signal provided by the reference filter to adjust the selected channel of the tunable filter.
    Type: Grant

  • Optimized multi-layer optical waveguiding system
    Patent number: 6542684
    Abstract: A single mode optical waveguide which is lithographically formed and employs polymeric materials having low propagation loss. The optical waveguide has a substrate, a polymeric, buffer layer having an index of refraction nb disposed on a surface of the substrate, a patterned, light-transmissive core layer having an index of refraction nc disposed directly on a surface of the cladding layer, and an overcladding layer having an index of refraction no on a top surface of the core, side walls of the core, and exposed portions of the buffer layer, with nb<no<nc and &Dgr;n=nc−no.
