Abstract: 본 발명은 파브리-페로 형태의 파장가변 필터에 관한 것으로, 하부 반사경, 하부 반사경 상부에 광축이 일치되도록 위치된 상부 반사경, 하부 반사경 상부에 위치되며 양측 종단부가 스페이서를 통해 하부 반사경에 고정된 구동체, 구동체의 양측 종단부에 각각 형성된 전극들, 구동체의 중앙부와 상부 반사경을 연결하는 막대구조체, 막대구조체 양측의 하부 반사경에 스페이서를 통해 각각 고정된 고정수단들, 막대구조체와 고정수단들을 연결하며 회전축 역할을 하는 탄성체들을 포함한다. 열팽창이나 전자기력, 혹은 외부의 힘에 의해 구동체의 휨이 발생되면, 탄성체를 회전축으로 지렛대 역할을 하는 막대구조체의 반대편에 연결된 반사경이 구동된다. 따라서 파장가변 범위가 기존보다 넓고 낮은 전력으로 구동할 수 있다. 또한, 두 반사경이 가까워지는 방향과 멀어지는 방향으로 양방향 구동이 가능하며, 구동체와 반사경이 분리되어 있어 전류에 의한 빛의 흡수 및 굴절률 변화가 최소화된다.
