Latest Patents
One of Jae Shik Choi's latest patents is an "Optical Measuring System with Arrayed Optical Receivers and Method Thereof." This invention provides a method for precisely measuring physical characteristics of light emitted from waveguides. It utilizes a plane optical detector with an array of pixels formed by a semiconductor fabrication process. The system measures various attributes of light, such as beam size, pattern, strength, focusing, collimation degree, and divergence angle, without the need for specific measuring means. The light is incident into the ends of the arrayed waveguides at uniform time intervals and is emitted from the other ends to reach the optical detectors, allowing for arithmetic definition of the physical characteristics.
Another significant patent is the "Optical Fiber Array Block Embedding Optical Device Therein." This invention includes an optical fiber array block that consists of at least one optical waveguide with an optical fiber zone and an optical device. An optical signal leakage window is formed at the optical waveguide, corresponding to the optical device. The design allows for the partial removal of the clad layer of the optical fiber, which is achieved through an ion implantation technique, enhancing the functionality of the optical device.
