  • Patent number: 8098999
    Abstract: A tunable filter may be utilized to successively tune to different wavelengths. As each wavelength of the wavelength division multiplexed signal is extracted, it may be successively power monitored. Thus, power monitoring may done without requiring separate power monitors for each channel. This results in considerable advantages in some embodiments, including reduced size, reduced complexities in fabrication, and reduced yield issues in some embodiments.

  • Publication number: 20080278445
    Abstract: According to one embodiment, a system includes a handheld device having a pixelated sensor, an optical filter for passing a predetermined frequency band of radiation to the sensor and a transmitter, an electronic equipment having a display, and at least two spaced-apart markers, where each of which are positioned proximate to the display. The markers provide radiation at the frequency band passed by the optical filter. The handheld device includes a processor coupled to receive image data of the markers from the sensor for computing coordinate data from the image data. The coordinate data requires less data than the image data. The processor is coupled to the transmitter to transmit the coordinate data to the electronic equipment. Other methods and apparatuses are also described.

    Abstract: Methods and apparatuses for rapidly tagging and recalling (via direct pointing) metadata from moving or still images are described herein. In one embodiment, data having full descriptions and hyperlinks are tagged to specific objects in moving images and the invisible hyperlinks move dynamically to continually track the associated object. In one embodiment, a pointing device can be used to point to objects in the scene, whether moving or stationary, and by appropriate action such as clicking or activating a button, be able to substantially immediately recall part or all of the metadata content that pertains to the object. Other methods and apparatuses are also described.

  • Patent number: 7189497
    Abstract: Multiple Bragg gratings are fabricated in a single planar lightwave circuit platform. The gratings have nominally identical grating spacing but different center wavelengths, which are produced using controlled photolithographic processes and/or controlled doping to control the effective refractive index of the gratings. The gratings may be spaced closer together than the height of the UV light pattern used to write the gratings.

  • Patent number: 7164478
    Abstract: A mounting platform provides support and packaging for one or more fiber Bragg gratings and electronic circuitry (e.g., heaters, coolers, piezoelectric strain providers, temperature and strain sensors, feedback circuitry, control loops), which may be printed on or on the mounting platform, embedded in the mounting platform, or may be an “off-board” chip solution (e.g., the electronic circuitry may be attached to the mounting platform, but not formed on or defined on the mounting platform). The fiber Bragg gratings are held in close proximity to the electronic circuitry, which applies local and global temperature and/or strain variations to the fiber Bragg gratings to, for example, stabilize and/or tune spectral properties of the fiber Bragg gratings so that spatial variations in the fiber Bragg gratings that result from processing and manufacturing fluctuations and tolerances can be compensated for.

  • Publication number: 20060221267
    Abstract: A projection display system may use a microdisplay that has pixels that are dedicated to only one narrow wavelength band. A suitable optical filter for each primary display color may be formed from a small number of optical layers, taking advantage of both the rounded profile and narrow range of the emission peaks in a typical projection light source. Thus, groups of pixels may be dedicated to each wavelength band of the display. A planarization layer may be coated on dichroic filter elements that are applied to a cover glass to provide the dedicated wavelengths for each pixel. The planarization layer may smooth out any surface irregularities resulting from the deposition of the dichroic layers on the cover glass.

  • Patent number: 7072546
    Abstract: A plurality of channels of a wavelength division multiplexing system may be subjected to dispersion compensation in a fashion which enables tuning of the compensation for each individual wavelength channel. Moreover, the tuning may be done in a space-efficient fashion. The chirped Bragg gratings may be formed, for example, on a planar light circuit.
