    摘要: The invention relates to an optical exposure system with partial polarization and collimation components that is useful for exposing alignment layers with light in order to align liquid crystals. The exposure system comprises at least one source of optical radiation, means for partially collimating said optical radiation, means for partially polarizing said optical radiation and means for transporting the substrate and radiation relative to one another. Other embodiments further comprise means for partially filtering the optical radiation and means for some portion of said optical radiation to be incident at an oblique angle relative to said substrate. Other embodiments include processes for aligning liquid crystals using the optical exposure systems.

    摘要: Arrayed waveguide grating can have one or both slab waveguides with relatively sharply folded optical paths and a mirror that provides the folding of the path. The folded optical paths through the slab waveguides can result in a more compact geometry of the waveguides through the device as well as smaller slab waveguides such that the device can be formed with a significantly smaller overall footprint. Also, arrayed waveguide gratings that cooperate with pivotable mirrors can adjust light passage through the waveguide in response to temperature changes to provide for thermally compensated operation of the device. Thus, very compact planar lightwave circuits filters are described that provide thermally compensated operation.

    摘要: A differential optical modulator for modulating an optical beam with a forward propagating path includes a polarization component to polarize the optical beam and provide redirection of the optical beam dependent on its polarization state, a polarization dependent path component to generate two temporally sheared orthogonal polarization components of the optical beam, a polarization exchange component that mutually exchanges the two orthogonal polarization states, a reflective switch component to modulate the two temporally sheared orthogonal polarization components of the optical beam by an applied control signal and to reflect the modulated optical beam back along the forward propagating path creating a return path, and a control means for providing an applied control signal to the reflective switch component.
