Sang Ho Park: A Pioneer in Patents

Meet Sang Ho Park, a brilliant inventor and engineer based in Daejeon, South Korea, who has gained well-deserved recognition for his remarkable contributions in the field of technology. Park has been a prolific inventor, having filed an impressive 263 patents throughout his illustrious career. Let's take a closer look at some of his most recent patents and contributions.

Optical Transmitter Module

One of Park's most notable recent inventions is an optical transmitter module that includes a directly modulated laser transmitter based on a directly modulated laser (DML) and an arrayed waveguide grating (AWG) chip. The transmitter allows for each of the one or more directly modulated laser chips to operate at a critical speed of 100 Gbps per channel or higher. The module also includes an impedance matching circuit and an RF-FPCB that transmits an RF modulating signal to the directly modulated laser chip array. The arrayed waveguide grating chip, on the other hand, includes optical waveguides that transfer multi-channel optical signals and a wavelength multiplexer that multiplexes the multi-channel optical signals. The transmitter and the chip are spaced apart from each other and optically coupled in chip-to-chip.

Method for Manufacturing Battery Module

Park's keen interest in creating innovative solutions has also led to a new battery manufacturing process that provides a simple, low-cost, and highly efficient method for producing battery modules. The process involves a module case in which an internal space is formed by a bottom plate and sidewalls, and an injection port that is formed in the bottom plate or the sidewalls. A plurality of battery cells exists in the internal space, and a resin layer contacts the bottom plate or the sidewalls while being in contact with the battery cells. In this method, a tape is attached to cover the injection port of the bottom plate or the sidewalls, and an injection device of a resin composition is mounted on the injection port while penetrating the tape. The resin composition is then injected into the mounted injection device. The method provides a simple process and at low cost without occurrence of a reverse discharge phenomenon.

Companies and Coworkers

Park's groundbreaking innovations have been widely recognized in the tech industry, and he has been fortunate enough to work with some of the most reputable tech companies and professionals in the field. He has worked for prominent organizations such as ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE and LG Chem, Ltd. His colleagues Byung Chun Park and Yoon Gyung Cho have also been mentioned in some of his patents.

Park currently has a long list of successful patents, but his work in the field of technology continues to inspire many engineers and inventors worldwide. The world is eager to see what other groundbreaking ideas he will come up with in the future.
