摘要 |
A metal film (12) is formed on the surface of a glass substrate (10) and etched to form a pair of electrodes (12a and 12b) which face each other with a certain gap therebetween (S11-S13). The substrate (10) is doped with germanium, etc, by using the electrodes (12a and 12b) as a mask to form a core part (14, S14). Then a high voltage is applied between the electrodes while ultraviolet radiation is applied and the core part (14) is subjected to ultraviolet-driven boring to give the optical nonlinearity to the core part (14, S15). The voltage application to the core part (14) having the optical nonlinearity is controlled to control a light transmitting through the core part (14).
