摘要： An example optical polarization controller can include a substantially planar substrate and a waveguide unit cell formed on the substantially planar substrate. The waveguide unit cell can include a first out-of-plane waveguide portion and a second out-of-plane waveguide portion coupled to the first out-of-plane waveguide portion. Each of the first and second out-of-plane waveguide portions can respectively include a core material layer arranged between a first optical cladding layer having a first stress-response property and a second optical cladding layer having a second stress-response property. The first and second stress-response properties can be different such that each of the first and second out-of-plane waveguide portions is deflected by a deflection angle.

摘要： A substantially planar waveguide for dynamically controlling the out-of-plane angle at which a light beam exits the waveguide. Generally, liquid crystal materials may be disposed within a waveguide in a cladding proximate or adjacent to a core layer of the waveguide. In one example, the waveguide may contain one or more taper regions such that the light beam exits the waveguide and propagates out-of-the-plane of the waveguide into an out-coupling medium at a propagation angle. In one example, the waveguide may contain one or more electrodes onto which one or more voltages may be applied. The magnitude of the propagation angle may be electronically controlled by altered by controlling or altering the magnitude of the one or more applied voltages.

摘要： An electro-optical device for processing an optical signal, comprises an electrode that is arranged and designed so that the optical signal at least partially intrudes the electrode when the optical signal is processed in the electro-optical device. An insulator is arranged adjacent to the electrode so that one face of the electrode contacts the insulator. A gate is arranged so that a voltage is applicable between the electrode and the gate such that a charge layer is induced on the face of the electrode that is contacting the insulator.

摘要： Disclosed is an optical delay element that makes use of a line-defect waveguide of a photonic crystal, in which long optical delay time and small group speed dispersion are rendered compatible with each other and in which waveform distortion that might otherwise be produced in processing an ultra-high speed signal is eliminated. Two line-defect waveguides 5 and 11, having different pillar diameters and group velocity dispersions of opposite signs, are interconnected by a line-defect waveguide 8, the pillar diameters of which are gradually varied from one 5 of the line-defect waveguides to the other line-defect waveguide 11, such as to compensate for group speed dispersion as well as to maintain an optical delay effect.
