Latest Patents

Kim’s recent patent work addresses technologies for generating polarized light and transmitting quantum information.

“Device for Generating and Splitting Polarized Light” describes an optical-waveguide-based device that accepts input light through one of four input waveguides. A series of optical splitters routes the light to an optical converter, which generates polarized light. The device produces four polarized-light states associated with elements of two mutually unbiased two-dimensional basis sets, a capability relevant to quantum information technologies.

“Quantum Information Transmitter, Quantum Communication System Including the Same, and Operating Method of Quantum Information Transmitter” describes a transmitter that uses a light-source driver, a light source, and an optical modulator. The driver produces signals at two levels, prompting the light source to generate signals with different average photon numbers. The modulator uses these signals to create a target signal and a decoy signal for quantum communication.
