[Abstract]:A mathematical model of half-wave voltage, working wavelength and temperature of Y-branch optical modulator is established. The half-wave voltage increases with the increase of operating wavelength and decreases with the increase of temperature. An automatic half-wave voltage measurement system based on 4-order Sagnac interferometer is designed and implemented. The on-line continuous measurement of half-wave voltage is realized. The relative measurement accuracy is 8.5 脳 10 ~ (-6). The half-wave voltage of Y-branch optical modulator in 1310nm and 1550nm band is measured by changing the working wavelength and ambient temperature with the adjustable laser source. The correlation between half-wave voltage and wavelength and temperature is determined by experiment. The results show that the half-wave voltage is linearly related to the wavelength and temperature in these two bands, and the wavelength correlation coefficient is positive, about 3.61 脳 10 ~ (-3) V / nm and 9.54 脳 10 ~ (-3) V / nm, respectively, and the temperature correlation coefficient is negative, about -1.76 脳 10 ~ (-3) V / 鈩，
