최근의 광-나노 기술의 발전에 힘입어, 테라헤르츠(THz)파 분야에 있어서 기술혁신이 이루어지고 있다. THz 시간영역 분광법, THz-QCL, 서브-THz 무선 통신, 서브-THz 전기신호 처리기술 및 THz 디바이스 등 다양한 THz파 관련 연구 성과가 폭넓게 전개되고 있어, 새로운 과학기술 분야의 하나로서, 또 신규산업의 개척을 짊어지는 것으로서 크게 기대되는 기술이다. 따라서 구체적인 장래 전망을 명확히 하기 위하여 THz 기술에 관한 기술동향을 분석하였다. 본 고에서는 기술동향 분석 결과를 토대로 THz파 기술의 현황과 전망에 관하여 설명하고, 차세대 핵심기술(core-technology) 창출을 목표로, THz 전자파, THz-photonics, THz-electronics 세 가지 연구분야의 총합적인 추진을 제안하고자 한다.
