  • Publication number: 20120128291
    Abstract: The present invention relates to an apparatus and method for creating an printed circuit board including one or more waveguides having one or more reflective surfaces. Waveguides are embedded within a printed circuit board. A reflective surface is formed within the embedded waveguides by mechanically milling the printed circuit board. The reflective surfaces enable intra chip, chip-to-chip, or chip-to-component optical interconnections through the waveguides embedded within the printed circuit board.

  • Patent number: 7760412
    Abstract: A modulator for modulating an optical signal is disclosed having a substrate, a support mounted to the substrate, and membrane attached to the support and defining an airgap between the substrate and the membrane. The membrane has at least three layers including a central layer having an index of refraction which is the square root of the index of refraction of the substrate. The thickness of the layers and the size of the airgap are optimized to maximize differential reflectivity of light incident on the membrane at a non-normal angle of incidence to the membrane when the membrane is either in an unbiased state or biased state. In one embodiment, the first, central, and third layers have corresponding thicknesses approximately equal to one-quarter, one-quarter, and on-half of a wavelength of the optical signal, respectively.

  • Patent number: 7387451
    Abstract: An apparatus and process for operating connectorless, free-space data porting optical structural composites with integrated optical or electrical busses are disclosed. Optical transceivers and fiber optic/coaxial cable are embedded into a foam-core composite sandwich structure which is infiltrated with vinyl ester resin. The embedded busses are composed of a signal source producing an optical free space signal, which is shone onto an optical/electrical bus containing a transceiver for converting this signal into another electrical or optical signal which then is imprinted upon a coaxial or fiber optic cable buried in the composite structure. The signal traverses the composite structure, then a transceiver converts the electrical/optical signal into a free space optical signal which shines out of the composite structure to an outside free space optical receiver. The optical free space signal is oriented to be received and transmitted at an angle of about 90 degrees relative to the composite material.

  • Publication number: 20070103928
    Abstract: An automated process for embedding optical fiber in woven composites includes embedding a woven fabric in resin using a vacuum infusion process to create a structural composite with integrated optical conduit with less than 0.8413 optical loss. The optical fiber is embedded in the woven fabric in both warp and weft directions. Optical fiber connectorization is done without polishing.

  • Publication number: 20050225835
    Abstract: The specification describes an improved Moving Anti-Reflection Switch (MARS) device structure that largely eliminates charge build up on the movable membrane, and reduces stresses that cause curling of the membrane. The improved device uses a movable membrane made of single crystal silicon.

  • Patent number: 6005262
    Abstract: A flip-chip bonded VCSEL CMOS circuit for preventing rearwardly emitted photons from the VCSEL from interfering with CMOS operation. The CMOS has bonding pads affixed thereto and spaced apart to define a region. The VCSEL is mounted to the bonding pads so that a lower mirror of the VCSEL is positioned between the bonding pads and in close proximity to an upper, major surface of the CMOS. A blocking layer is provided and is positioned within the region defined by the bonding pads to absorb or reflect rearwardly emitted photons from the VCSEL. In another embodiment, the blocking layer is removed and a photon detector is formed in the CMOS for collecting the rearwardly emitted photons for use in determining, inter alia, VCSEL laser power.
