  • Patent number: 8891922
    Abstract: A system and methods are disclosed for a hybrid silicon-organic scalable reconfigurable optical add-drop multiplexer. An embodiment of a scalable reconfigurable optical add-drop multiplexer (ROADM) includes an optical bus for optical signals of different wavelengths, a plurality of add/drop optical waveguides, and a plurality of ring resonators, each being optically coupled to the optical bus and to one of the add/drop optical waveguides. The ring resonators are coated with an organic electro-optic cladding layer and are configured to switch wavelength selected optical signals between the optical bus and the add/drop optical waveguides in response to control voltages applied to the organic electro-optic cladding layer. The individual ring resonators of the ROADM can be independently modulated and tuned to filter specific wavelengths.

  • Patent number: 7970244
    Abstract: An embodiment of a method for manufacturing an optical ring resonator device is disclosed. The method forms a ring resonator waveguide on a semiconductor substrate, forms an unoriented electro-optic polymer cladding over the ring resonator waveguide, and forms electrodes on the semiconductor substrate. The unoriented electro-optic polymer cladding is configured to change orientation under an applied electric field, and the electrodes are coupled to the optical ring resonator for manipulation of the electric field applied to the oriented electro-optic polymer cladding for rapid voltage tuning of its index.

  • Patent number: 7961988
    Abstract: A system and method are disclosed for a rapidly tunable wavelength selective ring resonator. An embodiment of a voltage-tunable wavelength selective ring resonator includes a ring-shaped waveguide formed on a semiconductor substrate, an electro-optic cladding layer formed over the ring-shaped waveguide, and voltage applying means for applying a voltage across the electro-optic cladding layer. The ring-shaped waveguide is configured to propagate optical signals having predetermined resonant wavelengths, the electro-optic cladding layer has a voltage-controlled variable refractive index, and the means for applying is configured to apply a wavelength-specific control voltage to the electro-optic cladding layer. The wavelength-specific control voltage will shift or tune the predetermined resonant wavelengths for the ring-shaped waveguide.
