Abstract
A tunable wavelength filter device that includes a light wave circuit having an input light wave path, an output light wave path, and a plurality of reflector elements between the input light wave path and the output light wave path that separate one or more wavelengths of an inputted light wave spectrum. A tuner component is positioned on the light wave circuit between the input light wave path and the output light wave path. The tuner component has an index of refraction that is chosen so as to alter the path of the light wave so that the resulting wavelength of the light wave that is output from the device is the desired wavelength.
