optical phase modulator

基本解释

The optical phase modulator does not suffer from the bias drifting problem as it does not need DC bias.
由于光相位调制器不需要直流偏置，不会遇到直流偏置漂移问题。
A piezoelectric ceramic, based on the converse piezoelectric effect, was used as optical phase modulator to design a fiber differential interferometer.
基于压电陶瓷的逆压电效应，采用压电陶瓷作为光相位调制器设计了光纤微分干涉仪。
The envelope of output optical signal after the phase modulator keeps stable and the optical signal can be used to carry uplink data back to the base-station.
在经过光相位调制器之后，输出光信号的包络保持不变，能被基站用来承载强度调制的上行信号。
