    Abstract: A novel organic light-emitting pixel structure provides improved contrast pixels suitable for use in high-contrast passive- and active-matrix displays. A dark, low-reflectance film is placed on a reflective or transparent substrate, which acts to absorb and/or trap ambient light impinging on the pixel and improving its contrast between on and off states. Optical scattering is reduced by fabricating a vertical wall around each pixel which effectively blocks out light emitted from adjacent pixels, and prevents the scattering of the pixel's own emitted light. Light is emitted through a transparent upper electrode, which allows the substrate to be non-transparent. An active-matrix display is thus built on a single silicon substrate, with the crystalline silicon transistors needed to drive the active-matrix fabricated alongside their respective pixels, and with the walls surrounding the pixels formed from the drive circuitry itself.

    Abstract: A time delay network for phased array antenna beam steering employs a waveguide network as the delay element in a monolithic integration with other optical and electronic elements on a single substrate. A plurality of optical time delay stages are cascaded to form the delay network, with each stage having a selectable delay time. Each stage preferably has a reference or nominal time delay branch, and at least one other finite time delay branch. The lengths of the delay waveguides vary from stage to stage, permitting a high time delay resolution with a relatively small number of separate waveguides. The desired time delay is selected either by directing the modulated laser light into only one of the waveguide branches in each stage by means of waveguide switches or by splitting the light into all the waveguide branches of a stage and then activating only the detector connected to the desired delay waveguide. A variety of cascading schemes and waveguide layouts can be used to implement the time delay network.

    Abstract: An optical-waveguide grating modulator is compatible with high-frequency electrical modulation signals of limited bandwidth. The modulator comprises an optical grating formed in an optical waveguide constructed from electro-optic (EO) material and an electrode that is an RF waveguide or RF transmission line that conducts a traveling-wave electromagnetic (EM) field and that contains a portion of the optical-grating waveguide with a continuous grating. The RF input modulation signal is coupled into an RF EM field that propagates through the RF waveguide or transmission line in a direction that is parallel to the direction the light propagates in the optical-grating waveguide and that EM field overlaps the optical-grating waveguide. The light travels along the optical-grating waveguide preferably at the same velocity as the RF EM field travels along the RF waveguide or transmission line.
