Patent

CA 2348313

There is provided a small and lightweight Fabry-Perot type optical tuner. By changing the distance between the reflector plates 3A and 3B with an applied voltage across said reflector plates 3A and 3B, wherein said reflector plates 3A, 3B are supported with coil springs 8A, 8B, and at the same time by changing the refractive index of the liquid crystal material 9, i.e. by utilizing both changes of distance d and refractive index n, an optical tuning can be obtained over a wide range of optical wavelength.
