Patents by Inventor Robert D. Te Kolste

Robert D. Te Kolste has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7453575
    Abstract: A spectrometer for use with a desired wavelength range includes an array of filters. Each filter outputs at least two non-contiguous wavelength peaks within the desired wavelength range. The array of filters is spectrally diverse over the desired wavelength range, and each filter in the array of filters outputs a spectrum of a first resolution. An array of detectors has a detector for receiving an output of a corresponding filter. A processor receives signals from each detector, and outputs a reconstructed spectrum having a second resolution, the second resolution being higher than any of the first resolution of each filter.
    Type: Grant

  • Patent number: 6600845
    Abstract: An integrated parallel transmitter includes an array of light sources, a corresponding array of diffractive elements splitting off a portion of the beam to be monitored, a corresponding array of power monitors for respectively monitoring each light source, and an array of couplers that couples light into a corresponding waveguide. The coupler is preferably a phase-matched coupler. All of the passive optical elements are integrated onto a single substrate or a plurality of substrates that have been bonded together on a wafer level.

  • Patent number: 6392808
    Abstract: An analog controlled angle diffuser and associated methods provide a wavelength insensitive diffuser with a controlled output. The diffuser has free formed shaped analog fringes, i.e., fringes which have a continuous cross-section from their peak to their termination. Preferably, the depth of the analog fringes will be at least 2&pgr;, even more preferably at least 2O&pgr;. Advantageously, the pattern of the diffuser is computer-generated.

  • Patent number: 6021106
    Abstract: A method of fabricating a diffractive optical element includes the steps of: etching a negative of a desired multi-level diffraction pattern onto a molding surface of a quartz master element using photolithography, assembling the master element as a portion of a mold, and injecting a plastic molding composition into the mold and against the molding surface of the master element to injection mold a diffractive optical element, whereby the optical element has the desired diffraction pattern on its surface. The diffraction pattern is preferably formed on the quartz master using VLSI photolithography.
