摘要： A spatial light modulator has a transmissive window with a transparent conductive film forming a ground plane and a direct drive backplane with a plurality of voltage gradient pixels. Each of the voltage gradient pixels has (a) resistive film, (b) resistive metal conductor frame on a boundary of the resistive film, and (c) conductive metal leads between a substrate of the direct drive backplane and the resistive metal frame. Differential voltages applied to the metal frame via the conductive metal leads generate a selective two-dimensional linear voltage gradient across the resistive film. A layer of liquid crystal material is disposed between the transmissive window and the voltage gradient pixels. Liquid crystal material of each voltage gradient pixel is responsive to an electric field generated by the voltage gradient to two-dimensionally alter phase of a wavefront incident thereon.

摘要： An apparatus for optically coupling a light source with a light-receiving end face of an optical waveguide comprises a lens for focusing a light beam emitted from the light source at a focal point on the light-receiving end face of the optical waveguide. An adaptive coupler, positioned in the optical path, is responsive to a beam steering control signal for steering and aligning the focal point relative to the light-receiving end face of the optical waveguide. In one form, the adaptive coupler comprises a pair of transparent substrates having confronting, parallel inner faces, the inner face of one of the pair of substrates carrying a beam intercepting, optically transparent, constant potential electrode and the inner face of the other of the pair of substrates carrying an electrically resistive, beam intercepting, optically transparent film. A pair of spaced apart electrodes in electrical contact with the film apply a linear voltage gradient along the film. An electro-optical phase shifting medium is disposed between the confronting inner faces of the substrates. The application of selected voltages to the electrodes creates a linear voltage gradient along the aforementioned film on the inner face of the one substrate resulting in a linearly varying electric field between that film and the constant potential electrode creating a corresponding linear variation in the refractive index of the liquid crystal medium and a linear wavefront tilt in the intercepting optical beam.
