Latest Patents
Larry Davis holds a patent for a "Wavelength locking scheme and algorithm for ultra-high density WDM system." This invention addresses the challenges of maintaining a stable laser wavelength in WDM systems with channel spacings of 25 GHz or less. The patent describes a method where light output from the laser is directed to a filtering element, such as an in-fiber Bragg grating or an etalon. Photodetectors are employed to sense the light transmitted through and reflected by the filtering element. A calculated ratio of photocurrents generated by the photodetectors is compared to a desired ratio, which corresponds to the temperature of the filtering element when it transmits the desired wavelength. This comparison allows for the adjustment of the laser temperature and wavelength, ensuring that wavelength variations due to temperature changes are compensated.
