Abstract

오랫동안 미개척 주파수 대역이었던 테라헤르츠 대역은 소자 및 시스템 기술 연구성과의 축적과 기술 성숙 과정을 거쳐, 최근 다수의 상용화 시스템이 출시되는 등 산업 분야에의 응용이 확산되었다. 특히, 투과 이미징이 가능한 테라헤르츠 이미징 시스템은 산업 분야에서 비접촉 비파괴 품질검사 분야 등에 많은 응용이 기대되고 있다. 이밖에 분광 기술에 기반을 둔 막 두께 측정 시스템, 초고속 통신 시스템 등도 향후 중요한 테라헤르츠 기술 응용 분야로 여겨지고 있다. 본고에서는 테라헤르츠 응용 기술에 관한 최근의 연구 동향을 간략히 살펴보고, 한국전자통신연구원 전파위성연구본부 테라헤르츠 창의원천연구실에서 주력해 온 포토닉스 기반 테라헤르츠 소자 및 시스템에 관해 상세히 소개한다.
