Title: Guk Jong Choi: Innovator in Optical Technologies

Introduction

Guk Jong Choi is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of optical technologies, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is the Total Internal Reflection Fluorescence Microscope (TIRFM). This invention involves a fluorescence microscope designed for imaging specimens containing fluorescent substances. The microscope features an excitation light source that emits light to excite the fluorescent substance, a de-excitation light source to de-excite the substance, and an optical body that overlaps the emitted lights before directing them toward the specimen. A solid immersion lens is also included, which refracts the light toward the specimen, allowing for total internal reflection at the lens's bottom.

Another notable patent is the Plasmonic Optical Waveguide using plasmonic coupling between a nano-aperture and a nano-particle. This invention includes a nano-aperture with a nano-scale opening for light entry and a single metal nano-particle positioned at the focal point of the aperture. This configuration generates plasmon coupling, resulting in a small, high-intensity light spot that significantly amplifies the light output compared to the incident light.
