Latest Patents

One of his latest patents is the "Mach-Zehnder interferometric optical modulator with shallow ridge waveguide structure and method for manufacturing the same." This invention includes a Mach-Zehnder interferometric optical modulator that consists of first and second lower clad layers, a core layer, an upper clad layer, a waveguide, and electrodes. The waveguide features an input waveguide, a waveguide divider, branch waveguides, and a waveguide combiner. Each branch waveguide has first and second connection regions linked to the waveguide combiner and the waveguide divider, respectively. Additionally, it includes a phase shift region with a cross-section of a reverse mesa structure.

Another notable patent is the "Antenna structure with dielectric lens and triangular electrodes." This antenna structure comprises a dielectric lens, an antenna substrate on the dielectric lens, and antenna electrodes on the antenna substrate. Each antenna electrode consists of a wire electrode and an empty plane shaped like a triangle defined by the wire electrode. This design effectively reduces periodic reflection of high-frequency signals, suppresses periodic gain reduction, and provides flat gain characteristics across a wide frequency band.
