  • Patent number: 10211602
    Abstract: An optical device may include a semiconductor laser chip to independently generate four laser beams at different wavelengths. Each laser beam, of the four laser beams, may be directed to a respective optical output of the optical device with a sub-micron level of tolerance of each laser beam relative to the respective optical outputs of the optical device, and each laser beam, of the four laser beams, may be associated with a different optical path from the semiconductor laser chip to the respective optical output of the optical device. The optical device may include a lens to receive each of the four laser beams. The lens may be positioned to direct each laser beam, of the four laser beams, toward the respective optical output of the optical device. The optical device may include an optical isolator to receive each of the four laser beams.

  • Patent number: 10162135
    Abstract: The invention relates to an optical transmitter assembly (OTA) for vertical coupling of light into a chip, and to a method for manufacturing the OTA. The OTA includes a laser diode, a microlens and a turning mirror mounted at a top face of a supporting substrate within a sealed enclosure, and an optical component, such as an optical isolator, a polarizer, or a microlens disposed in a substrate cavity that opens to the back face of the substrate. The optical component may be placed into the cavity after the enclosure is sealed.

  • Patent number: 7769295
    Abstract: A micro-optic dual beam-splitter assembly comprises at least two beam-splitter optical filters and at least one photoreceptor. Each of the beam-splitter optical filters comprises an optical substrate having at least a coated or uncoated optical tap surface and a filter surface carrying a thin-film optical filter. The thin-film optical filters are substantially normal to the optical path from an optical signal source. Each of the optical tap surfaces is operative as an optical beam splitter to tap off an optical tap signal. The one or more photoreceptors are arranged to receive both or at least one of the optical tap signals. The tap signals comprise a portion of the optical signals passed along the optical path to the optical filter chips. The filter chips are cooperatively transmissive to an optical signal output port of a selected set of wavelengths received from the optical signal source along the optical path, and are reflective of other wavelengths.

  • Publication number: 20030185259
    Abstract: An apparatus and a method is provided for frequency identification and laser locking by sending optical signals of a laser through a set of optical filters. The signal power transmitted by the filters is measured and the resulting set of powers normalized with respect to a reference power. The multidimensional measurement output curve of the set of filters is nondegenerate. The set of measurements is compared to a set of points in a calibration table or constellation, which results in the identification of the frequency of the laser.

  • Patent number: 6517284
    Abstract: A reservoir drainage system drains water away from a soil around a footing foundation of a structure and collects the drained water outside of the same. The system includes a network of drainage tubes externally rounding a perimeter of the footing foundation and connected to a collecting tube. The latter collects the drained water from the network and directs it by gravity into a collecting reservoir member located outside of the structure below a bottom level of the foundation. The drainage network has a first part that is substantially horizontally leveled and longitudinally runs along a first portion of the perimeter and generally against the same. The network also includes a second part that continues the first part, is connected to it at an upper end and longitudinally runs along a complementary second portion of the perimeter. The second part slightly outwardly diverts away and is downwardly inclined from the footing foundation down to a lower end connected to the collecting tube.
