Patents by Inventor BRIAN DEAN TAYLOR

BRIAN DEAN TAYLOR 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).

  • Wavelength and power monitor for WDM systems
    Patent number: 8565602
    Abstract: Consistent with the present disclosure, a transmitter is provided that includes first and second stages of wavelength locking circuitry. The first stage includes a tunable optical filter that sweeps through the spectrum of a WDM signal at a predetermined rate. A first photodiode senses a tapped portion of the output of the tunable filter. The remaining light is fed to the second stage, which includes a second optical filter, typically having a fixed transmission characteristic. A second photodiode senses the light that passes through the second filter. By sweeping the WDM spectrum the tunable filter can be used to identify the peaks in the WDM spectrum, with each peak corresponding to an optical signal wavelength and occurring at a particular time interval during the sweep.
