Patent

CA 2266682

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).

Une couche mince de métal (12) est formée sur la surface d'un substrat en verre (10) et gravée afin de former une paire d'électrodes (12a, 12b) se faisant face avec un certain espacement intermédiaire (S11 - S13). Le substrat (10) est dopé au germanium, etc., à l'aide des électrodes (12a et 12b) et d'un masque pour former une partie centrale (14, S14). On applique ensuite une haute tension entre les électrodes tout en appliquant un rayonnement ultraviolet, et on soumet la partie centrale (14) à un perçage par ultraviolets afin de donner à la partie centrale (14, S15) la nonlinéarité optique. L'application de tension à la partie centrale (14) présentant la non linéarité optique est régulée afin de réguler une transmission de lumière à travers la partie centrale (14).
