  • Actively-controllable optical switches based on optical position sensing and applications in optical switching arrays
    Patent number: 6580846
    Abstract: Controllable optical switches in response to feedback signals from optical position sensors that measure switch orientations. The optical position sensors may include local sensors that monitor and measure orientations of individual switches and global sensors that monitor and measure overall alignment of signal beams. Such switches may be used to form non-blocking switching arrays.

  • Versatile optical switching for wavelength-division multiplexed system
    Patent number: 6535312
    Abstract: Scalable and modular WDM systems to provide a number of processing functions which include, among others, signal detection, signal monitoring, wavelength conversion, signal regeneration, and generation of new WDM channels. Such WDM systems include a platform with an optical switching network and module slots for engaging WDM modules of different processing functions. Both protocol transparent and opaque WDM modules may be included in such a WDM system to provide versatile applications.

  • Stabilization of a laser array module
    Patent number: 6501773
    Abstract: A laser array system is described. The system includes a plurality of lasers, a switching mechanism, a wavelength locking mechanism, and a laser parameter feedback control. Each laser provides a collimated beam having certain wavelength and power. The beam has at least two parts, first part of the two parts used for stabilization of the wavelength and power. The switching mechanism is configured to receive and sequentially select the first part of the collimated beam from the plurality of lasers. The wavelength locking mechanism is configured to monitor and measure a drift of the wavelength and power of a selected laser. The laser parameter feedback control is configured to adjust laser parameters of the selected laser.
