인공지능, 빅데이터 등 디지털 기술로 촉발되는 초연결 기반의 지능화 혁명시대에 요구되는 ICT 소재 및 부품 연구 수행
The convergence of information science, semiconductor photonics and electronics is poised to profoundly affect the human life. Two pronounced examples are the recent progress in broadband communications networks fueled by internet and wireless mobile communications; both of them are based as much on high speed semiconductor optoelectronics and computing power of modern digital computers as information processing technology. Natural advantages of III-V compound semiconductors such as efficient generation and detection of optical waves and high carrier mobilities, high quality heterostructures can be fully enjoyed by optoelectronic components generating and detecting optical signals, and electronic components requiring ultra-high frequency, ultra-low noise or high power driving capabilities.
The achieve high performance and low cost transmitter and receiver module, it is required to integrate III-V optoelectronic chips, Si electronics, passive microwave circuits, and passive optical waveguide in the same module. Microwave optoelectronics group focuses on design, fabrication, and development of characterization methodologies of high-speed optoelectronic semiconductor devices, circuits, and their heterogeneous integration. Researches on ultra-high speed digital circuits based on InP-E/DHEMT technology, design and fabrication of optoelectronic receiver circuits and photonic integrated circuits using high-mesa optical waveguides are now pursued.
