1. Optical wavelength tuning method, wherein an optical tuning of the Fabry-Perot type optical cavity to the desired wavelength of the optical signals is made to obtain the desired optical output by controlling the distance between opposing reflector plates of said Fabry-Perot type optical cavity with a distance changing unit and concurrently by controlling the refractive index of the liquid crystal material having a refractive index changeable by the applied electric field with an electric field application unit and filled in between said reflector plates.
