摘要： An optical device includes an optical port array having first and second optical inputs for receiving optical beams and a first plurality of optical outputs associated with switching functionality and a second plurality of optical outputs associated with channel monitoring functionality. A dispersion element receives the optical beam from an input and spatially separates the beam into a plurality of wavelength components. The focusing element focuses the wavelength components.

摘要： A method is provided for reducing flicker arising in pixels along an axis of a liquid-crystal based array such as a LCoS array. The pixels along the axis exhibit a common gray scale level. In accordance with the method, a plurality of digital data command sequences are selected that each drive a pixel at the common gray scale level. A first of the plurality of digital data command sequences is applied to a first pixel along the axis. A second of the plurality of digital data command sequences is applied to a second pixel along the axis. The second pixel is adjacent to the first pixel. The first and second digital command sequences give rise to voltages being applied to the two pixels which have frequency components that are opposite in phase and equal in magnitude.

摘要： An optical device in which crosstalk due to scattering is reduced includes an optical port array having at least one optical input for receiving an optical beam and at least one optical output. The input and outputs extend along a common axis. A dispersion element receives the optical beam from the optical input and spatially separates the optical beam into a plurality of wavelength components. A focusing element focuses the plurality of wavelength components and a programmable optical phase modulator receives the focused plurality of wavelength components. The modulator is configured to steer the wavelength components to a selected one of the optical outputs. The programmable optical phase modulator is oriented with respect to the optical port array so that an axis along which the optical beam is steered is non-coincident with the common axis along which the input and outputs extend.

摘要： An optical device includes an optical port array, a first walk-off crystal, a first half-wave plate, a second walk-off crystal and a segmented half-wave plate. The optical port array has a first and second plurality of ports for receiving optical beams. The first walk-off crystal spatially separates the beams into first and second portions that are in first and second orthogonal polarization states, respectively. The first portions are walked-off by the first walk-off crystal and the second portions pass therethrough without being walked-off. The first half-wave plate rotates the polarization state of the first and second portions of the optical beams. The second walk-off crystal is oriented in an opposite direction from the first walk-off crystal such that the second portions are walked-off by the second walk-off crystal and the first portions pass therethrough without being walked-off. The segmented half-wave plate receives the first or second portions of the beams.

摘要： A method of monitoring at least one optical wavelength component of a WDM optical signal being routed through a wavelength selective switch (WSS) includes directing an optical wavelength component from a given input port of the WSS to a selected output port with a selected amount of attenuation. A rejected portion of the optical wavelength component giving rise to the selected amount of attenuation is directed to an optical monitor associated with another output port of the WSS. A power level of the optical wavelength component is determined by pre-calibrating a proportionality between the power level of the wavelength component and the power level of the rejected portion that is directed to the optical monitor.
