Abstract:
1. A tunable wavelength filter device comprising: a light wave circuit that includes 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; and a tuner component that tunes the tunable wavelength filter device to output a desired wavelength of the inputted light wave spectrum, the tuner component comprising an interchangeable light path substance positioned on the light wave circuit between the input light wave path and the output light wave path; wherein the interchangeable light path substance is a polymer material that has an index of refraction that guides the light path of the inputted light wave spectrum as it passes through the interchangeable light path substance to output a desired wavelength of the inputted light wave spectrum, and wherein the tuner component is retunable by replacing the interchangeable light path substance with a second interchangeable light path substance having a different index of refraction or by combining the interchangeable light path substance with the second interchangeable light path substance.
