An optical waveguide film includes a film including a clad layer and a core layer covered by the clad layer; and an adhesive layer formed at least on one surface of the film, having a rough structured surface having an arithmetic mean surface roughness of 0. A brace extends from an inner surface of the body or from a perimeter weight system to a contact point on the rear surface of the face. Waveshaping curves, waveshaping parameters, hysteresis characteristics and hysteresis parameters may be recalled from stored program control or modulated in real-time by arbitrary control signals, including those derived from the original input signal.
