Brian Shia 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).

  • Optical amplifier controller
    Patent number: 9007682
    Abstract: A controller is configured to determine a first amount of current associated with a first power level. The controller is configured further to generate a digital pulse signal based on the first amount of current, where the digital pulse signal may have a second power level and an associated duty cycle. The controller is configured further to convert the digital pulse signal into a second amount of current and output the second amount of current as a pulse signal based on the duty cycle.
    Type: Grant

  • Fast power transient supression in constant power-mode controlled optical amplifiers
    Patent number: 7961380
    Abstract: The specification describes an improved approach to suppressing fast transients in optical amplifier systems. The approach relies on operating the amplifier in an automatic power-mode control with an extra loss component. It is applicable to optical amplifiers based on rare earth amplifier media, such as erbium doped fiber amplifiers (EDFAs).
