Latest Patents

One of his latest patents is the "Electro-optic modulator with resonator." This invention features an electro-optic modulator structure designed for use in narrowband optical subcarrier systems. Unlike traditional modulators, a traveling wave is established across the active region of the device, which enhances performance. The use of a directional resonator structure prevents reverse-traveling waves, allowing for a more efficient application of the electric field to the traveling optical wave. This design enables tuning to operate at any frequency, regardless of the active region's length, and mitigates optical transit time effects.

Another significant patent is the "Optical duobinary single sideband modulator." This apparatus modulates information-bearing symbols onto an optical carrier using a polybinary coder. The result is an envelope compatible polybinary signal that improves both polybinary signaling and optical single sideband. This innovation combines the advantages of SSB modulation with the benefits of duo-binary coding, enhancing performance in optical communications.
