Abstract: 본 발명은 미소기전집적시스템(MEMS: Micro-Electro-Mechanical System) 형태의 파장가변 필터에 관한 것으로, 광축이 정렬된 두 개의 광섬유 혹은 광 도파로, 상기 광섬유 혹은 광 도파로 앞단에서 빛을 모아주는 두 개의 렌즈, 하나의 기판에 형성된 두 개 혹은 그 이상의 반사경, 적어도 하나의 상기 반사경을 지지하는 열구동체를 포함하며, 전류의 흐름에 따른 열구동체의 열팽창에 의해 상기 반사경이 구동된다. 반사경들이 하나의 기판에 모두 형성되므로 서로 다른 기판에 형성된 반사경을 조립하는 구조에 비하여 제작 과정이 간단하고 초기 공진 파장을 정밀하게 조절할 수 있으며, 열구동체에 직접 전류를 흘려 열팽창시키므로 적은 소모 전력으로 구동이 가능하다. 또한, 반사경을 움직이는 데 정전력을 이용하지 않으므로 반사경들 사이의 고착 현상이 일어나지 않아 정전구동에 의한 파장가변 필터에 비하여 더 넓은 범위의 파장가변이 가능하며, 평면 형태의 반사경이 서로 평행하게 배열되므로 광정렬이 쉽고 선폭이 일정하며 삽입 손실이 적다.
