Professor Sangshin Lee's Research Team (Department of Electronic Engineering)

won the Best Paper Award at the KIEE Summer Conference 

Kwangwoon University research team led by Professor Sang-Shin Lee (Department of Electronic Engineering) participated in the 53rd Summer Conference of the Korean Institute of Electrical Engineers was held at the Yeosu Expo Convention Center held on July 13-16, 2022. Student Woo-Bin Lee (6th semester of doctoral program) presented a thesis as a research topic on “Electro-Optic Devices Based on Thin-Film Lithium Niobate-Silicon Nitride (Woo-Bin Lee, Sang-Shin Lee)”. In recognition of his research achievements he received the best paper award.

With increasing demand for high bandwidth, frequency allocation, low-loss data communication, and miniaturization, optical modulators are an essential part of modern technology. An optical modulator refers to a device that loads a signal from a transmitter to light when optical fiber or free space in the optical frequency band is used as the transmission medium. In this study, the research team presented the design, verification and various applications of a modulator using a lithium niobate thin film deposited with silicon nitride. Additional research and development will be carried out for the proposed technology to be applied to LiDAR in the future. This research was carried out through the support project for university-focused research institutes in science and engineering supported by the Ministry of Education and the mid-level researcher support project supported by the Ministry of Science and ICT.

The KIEE Summer Conference is the largest of the domestic electrical (engineering) academic conferences, and a total of 1226 academic papers and R&D results were presented.

Currently, Professor Sang-Shin Lee is the research director of the 'Nano Device Application Lab'. Since joining Kwangwoon University in 2002, he has been actively conducting research on various topics such as optical communication devices, nano optical devices and optical sensors, and has published about 160 papers in leading overseas SCI journals. He is also conducting research on core technologies related to the 4th industrial revolution, such as silicon photonics-based LiDAR sensor modules for autonomous driving and wireless optical communication devices, with support from the Korea Research Foundation and others.
