Title: Kyoung Hak Mun: Innovator in Optical Communication Systems
Introduction
Kyoung Hak Mun is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of optical communication, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is titled "Receiving method and receiver device for a coherent optical communication system." This invention discloses a receiver device that includes an optical splitter to divide a received optical signal into at least two paths. It features a first amplifier that amplifies a second optical signal from the split signals, followed by a second amplifier that further amplifies the output signal. The coherent receiver module then mixes and detects the output signal, providing advantages such as suppressing frequency offsets and minimizing phase noise. This device is designed for low-cost manufacturing without the need for additional optical sources or fibers.
Another notable patent is the "Optical network unit capable of reducing optical beat interference and method for controlling the same." This invention is part of an OFDMA-PON system and aims to reduce optical beat interference (OBI). The optical network unit includes a signal generator that creates an electrical signal carrying transmission data, an RF tone generator, a combiner to merge the electrical signal and RF tone, and a photoelectric converter that transforms the combined signal into an optical signal.
