Latest Patents

One of his latest inventions is a "Multiple-cavity optical filter using change of cavity length." This invention describes a tunable optical filter designed for use in optical communication systems. The filter features a pair of resonator cavities that are cascaded. The lengths of these cavities change simultaneously with the adjustment of a piezoelectric sleeve, which contacts the reflective surfaces of each cavity through spacers. This innovative design allows the reflecting surfaces to move along a single axis in response to a single control signal. When optical signals pass through the two cavities, the resonator cavity resonates at a desired wavelength when the ratio of the cavity lengths is adjusted to a predetermined ratio of integers.

Another significant patent is the "Simplified double-cavity tunable optical filter using voltage-dependent." This tunable optical filter consists of several cascaded resonator cavities, each containing electro-optic material. The resonator cavities resonate at a specific wavelength when the index of refraction of the electro-optic material is altered to a predetermined value in response to a single control voltage. This adjustment is achieved by applying the control voltage to one of a pair of electrodes located on opposite sides of the resonator cavities.
