“…However, research on the MIOC response error is still preliminary, such as phase drift [6], center wavelength stability [7], etc. Considering the voltage-phase conversion, some reports have focused on the halfwave voltage, especially a lower working voltage [8,9], temperature fluctuation [10,11,12], and wavelength correlation [12]. For example, Ran Ding et al reported a sub-1 V halfwave voltage by a better radio frequency design and more active polymer doping [8].…”

“…Xianhui Mao et al presented a halfwave voltage reduction when the temperature was increased [10]. Additionally, Fuling Yang et al described the positive correlation between the halfwave voltage and wavelength [12]. However, as far as we know, there are no published works focused on the frequency dependence of halfwave voltage, due to nonlinear effects and structural resonance.…”

The multifunction integrated optical chip (MIOC) is one of the most critical parts of the interferometric fiber optic gyroscope (IFOG), and research on the halfwave voltage of the MIOC is meaningful for a high-precision IFOG. In this paper, the correlation between the frequency and halfwave voltage, which affects the interference light intensity of IFOG, is presented theoretically. A widespread measurement method for frequency dependence of the halfwave voltage, based on lock-in amplification and sinusoidal modulation, is proposed. Further, the measurement result and the oscillation of interference light intensity in the Sagnac interferometer are presented, which are in great agreement with the theory. This paper proposes the frequency dependence of the halfwave voltage and provides a new error research direction for the improvement of the MIOC in a high-precision IFOG.
