摘要： A fiber-optical, wavelength selective switch, especially for channel blocking applications. The input signal is converted to light beams having predefined polarizations relative to the plane in which optical manipulation of the beam is performed. The beams are then preferably laterally expanded in this system plane only, and then spatially dispersed in the beam expansion plane, preferably by means of a diffraction grating. The light is directed through a polarization rotation device, preferably a liquid crystal cell, pixelated along the wavelength dispersive direction such that each pixel operates on a separate wavelength. When the appropriate control voltage is applied to a pixel, the polarization of the light signal passing through that pixel is rotated. The wavelength dispersed beams from all of the pixels are then recombined, and are passed towards a polarization selective device, aligned such that only selected polarization components are transmitted out of the switch.

摘要： A fiber-optical, wavelength selective switch, especially for channel routing with equalization and blocking applications. The input signals are converted to light beams having predefined polarizations (41). The beams are then laterally expanded (43), and then undergo spatial dispersion in the beam expansion plane. The different wavelength components are directed through a polarization rotation device, pixilated along the wavelength dispersion direction such that each pixel operates on a separate wavelength. Each beam is passed into a pixilated beam steering array (48), for directing each wavelength to a desired output port. The beam steering devices can be MEMS-based or Liquid crystal-based, or an LCOS array. When the appropriate voltage is applied to a pixel and its associated beam steering element, the polarization of the light passing through the pixel is rotated and the beam steered to couple to the selected output port.

摘要： The present invention discloses a novel Polymer-Dispersed Ferroelectric Liquid Crystal Display (PDF LCD). The active matrix LCD such as a TFT LCD, the solution of low response speed of nematic LCD, requires very high production costs. The FLCD utilizing ferroelectric liquid crystal exhibits highly rapid response speed, but results in an unstable structure, difficult fabrication, and incompetency of expressing gray scales. Meanwhile, the PD LCD exhibits a simple structure, wide viewing angle and high strength, but low contrast thereof disqualifies it for image displays. The present invention combines the PD LCD and FLCD, that is, droplets of ferroelectric liquid crystal are dispersed in a polymer matrix to include the merits and compensate for the shortcomings of each. As a result, there is provided a novel PDF LCD having very rapid response speed, resistance to external shock or heat, and high contrast. Moreover, the present PDF LCD does not exhibit bistable characteristics to be able to express gray scales, and thus it is suitable for fabricating large area color image displays.
