Objective: Development of state-of-the-art integrated quantum nano-optical devices utilizing semiconductor processes.
Applications: Highly applicable to the field of quantum information and all fields of science and engineering utilizing light.
Comprehensive research on integrated optics and metamaterial devices applicable to quantum information fields
- Process: Nano-optical device process utilizing the entire semiconductor process (E-beam/Photo Lithography, Etching, Deposition, Wet-chem, Wire-bonding, etc.)
- Design: Integrated nano-optical device design through optical simulation, optimization, and deep learning
- Measurements: Precision optical measurements of quantum signals, building fiber optic and spatial light optical setups.

Starting from October 2022, we have started working at the Korea Institute of Science and Technology and have not yet graduated. Our lab researches integrated quantum photonic devices using semiconductor processes (domestic top-level nanoprocesses), optics, and programming. This research field is deeply related to the following domestic companies.
- Semiconductor Process: Samsung Electronics, SK Hynix, DB HiTek and semiconductor-related companies
- Optical device design (optimization/AI) and optical measurement: Samsung Electronics, LG Innotek, LG Electronics, Samsung Electro-Mechanics, KT, SKT, etc.
