OPTICAL MODULATOR AND MODULATION METHOD |
摘要 |
An optical modulator comprises an electrode 21 which applies to an optical waveguides 12 of a Mach-Zehnder type optical interference system a first electric signal based on an alternating current signal S 1 and a direct current bias V 1 , an electrode 22 which applies to an optical waveguide 13 of the Mach-Zehnder type optical interference system a second electric signal based on an alternating current signal S 2 and a direct current bias V 2 , and a bias setting section 41 which sets average direct current levels of the first and second electric signals based on signal frequency information D 1 which indicates a magnitude relation between a maximum frequency of the alternating current signal S 1 and a maximum frequency of the alternating current signal S 2.
