Abstract
A Ge-added SiO thin film ( ) is formed on a glass substrate ( ), and metal film ( ) is formed thereon (S to S ). By etching the metal film ( ), a pair of electrodes ( ) mutually opposed at a predetermined interval is formed(S ). An insulating thin film ( ) is formed on the insulating film ( ) and the electrodes ( ) (S ). While applying ultraviolet radiation, a high voltage is applied between the electrodes ( ) to perform ultraviolet excitement polling to impart an optical nonlinearity to a channel region ( )(S ). By controlling the voltage application to the channel region ( ) having the optical nonlinearity, the light transmitted through the channel region ( ) is controlled. Thus, an optical nonlinear waveguide for propagating single mode light is formed on a glass substrate.
