Latest Patents

One of Min-Chul Oh's latest patents is an "Optical waveguide intensity modulator using electro-optic polymer." This invention utilizes the electro-optic effect and optical birefringence induced from a poling process of a nonlinear polymer thin-film. The modulator is constructed by a series combination of a TE/TM mode selector, a TE or TM mode converter, and another TE or TM mode selector. The integration of these components onto a single substrate improves the efficiency of the device by eliminating the need for elements that cause optical losses, such as optical isolators or couplers.

Another notable patent is the "TE-TM mode converter on polymer waveguide." This invention employs electro-optic birefringence and the electro-optic effect as a non-linear optical waveguide medium. The design allows for the formation of an optical director at a 45-degree angle to the electrical direction of the TE and TM modes. This enables effective switching between modes when the waveguide receives incident light. The adjustments in the poling electrode length and birefringence allow for various electro-optic polarization states, enhancing the versatility of the waveguide.
