Latest Patents
John Oldham holds a patent for his invention titled "Photonic filtering of electrical signals." This patent describes a filter and a method for filtering high-frequency electrical signals using photonic components. The filter consists of a serially fiber-coupled laser source, a modulator, a filter, and a photodetector. The electrical signal is applied to the modulator, and the modulated light propagates through the filter, which is designed to pass both a modulated sideband and a portion of light at the carrier frequency of the laser. The photodetector then detects a signal at the beat frequency between the carrier and sideband signals after they have passed through the filter. This design eliminates the need for a separate optical branch for light at the carrier frequency, simplifying the filter's construction and enhancing its stability and reliability. John Oldham has 1 patent to his name.
