The Nonlinear Optics & Photonic Devices for Quantum Applications (NOPD) Laboratory, founded in 2013, conducts cutting-edge research at the crossroads of nonlinear optics, quantum optics, and mid-infrared photonic technologies. Our work centers on three main areas: Mid-infrared photonic devices and fiber-optic components that exploit nonlinear optic processes; Quantum-light source development and characterization for quantum-information technologies; Experimental investigations in quantum optics, quantum communication, and quantum sensing. Building on the legacy of conventional optical communications, we actively pursue emerging applications in quantum information processing, precision sensing, defense, and security. By merging nonlinear photonics with quantum technologies, the NOPD Laboratory strives to advance next-generation photonic and quantum systems.

2013년에 설립된 양자 응용을 위한 비선형 광학 및 광자 장치(NOPD) 연구실은 비선형 광학, 양자 광학 및 중적외선 광자 기술의 교차점에서 최첨단 연구를 수행합니다. 저희 연구는 세 가지 주요 영역에 중점을 둡니다: 비선형 광학 프로세스를 활용하는 중적외선 광자 장치 및 광섬유 구성 요소; 양자 정보 기술을 위한 양자 광원 개발 및 특성화; 양자 광학, 양자 통신 및 양자 감지에 대한 실험적 연구. 기존 광통신의 유산을 바탕으로, 저희는 양자 정보 처리, 정밀 센싱, 국방 및 보안 분야의 새로운 응용 분야를 적극적으로 추구합니다. 비선형 포토닉스와 양자 기술을 융합함으로써 NOPD 연구실은 차세대 광자 및 양자 시스템 발전을 위해 노력합니다.
