Abstract
An optical module includes a mirror which reflects input light and which outputs output light; and a mirror control section which is opposite to the mirror and which controls, at the time of the input light being reflected from a reflecting surface of the mirror, the reflecting surface by distorting the reflecting surface according to voltage applied to the mirror so as to output the output light an optical coupling characteristic of which changes. By using this optical module, the optical coupling characteristic of the output light changes.
