Latest Patents

Marshall T Depue holds a patent for a "Wide-band tunable optical filter using electroholograms written into photorefractive crystals." This tunable optical filter utilizes multiple electroholographic (EH) gratings with different center wavelengths to filter an optical signal over a wide wavelength range. The EH gratings are interconnected, allowing an input optical signal to pass through at least one of the EH gratings. The activation and tuning of the EH gratings are managed by electrode pairs controlled through a voltage controller. The tunable optical filter is designed for coarse tuning by activating the EH gratings that encompass the desired center wavelength and for fine tuning by adjusting the voltage applied across the activated EH gratings.
