  • Publication number: 20090142016
    Abstract: According to one embodiment, a circuit element for a plasmonic circuit is formed using a dielectric layer having two portions, each characterized by a different electric permittivity. The dielectric layer is adjacent to a metal layer, with the interface between the layers defining a conduit for propagation of surface plasmons. A dielectric boundary between the two portions of the dielectric layer is shaped to enable the circuit element to change one or more of propagation direction, cross-section, spectral composition, and intensity distribution for a beam of surface plasmons received by the circuit element.

  • Patent number: 7502160
    Abstract: A laser projector having a configurable spatial light modulator (SLM) adapted to display various spatial modulation patterns and redirect illumination from a laser to form an image on the viewing screen. The laser projector drives the SLM to change spatial modulation patterns at a rate that causes the corresponding sequence of projected images to fuse to mitigate appearance of speckle in the resulting fused image. The SLM can be designed to redirect the illumination using either diffraction or specular reflection of light from the displayed spatial modulation pattern. In one embodiment, the SLM is a MEMS device having an array of individually addressable mirrors supported over a substrate and adapted to move (e.g., translate and/or rotate) with respect to the substrate.

  • Publication number: 20080219579
    Abstract: Methods and apparatus are provided for compressed imaging by performing modulation in a pupil plane. Image information is acquired by modulating an incident light field using a waveplate having a pattern that modifies a phase or amplitude of the incident light field, wherein the waveplate is positioned substantially in a pupil plane of an optical system; optically computing a transform between the modulated incident light field at a plane of the waveplate and an image plane; and collecting image data at the image plane.

  • Publication number: 20070228869
    Abstract: An electro-mechanical actuator includes a comb drive and a deformable connector. The comb drive has a first capacitor plate and a second capacitor plate. The capacitor plates have teeth capable of inter-digitating. The deformable connector is configured to apply a mechanical restoring force to the first capacitor plate. The deformable connector is configured to restore the first capacitor plate to be at an equilibrium rest position in response to no control voltage being applied across the capacitor. The comb drive is more engaged at the equilibrium rest position than at a mechanical stability threshold of the comb drive. The capacitor plates are disengaged at the equilibrium rest position.

  • Patent number: 7206117
    Abstract: An apparatus having a plurality of arrayed MEMS devices, each device having a parallel-plate actuator and a reflective plate, both of which are mechanically coupled to a flexible beam attached between two anchors. Advantageously, the use of parallel-plate actuators in the apparatus alleviates stringent requirements for the alignment of lithographic masks employed in the fabrication process. In one embodiment, each flexible beam has a relatively small thickness and a relatively large length to effect a relatively large displacement range for the corresponding reflective plate. Movable electrodes of different parallel-plate actuators are configured to act as an electrical shield for the flexible beams, which reduces inter-device crosstalk in the apparatus. Reflective plates of different MEMS devices form a segmented mirror, which is suitable for adaptive-optics and/or maskless lithography applications.
