Abstract

PURPOSE: Both the capacity element and the capacity adjustment part are provided and then insulated electrically to each other. Then the mono-color beam is irradiated to the apacity adjustment part, i.e., the photo ariable capacity diode, and thus the capacity can be made ariable by plural mono-color beams given from the light source.
