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.
由於光相位調制器不需要直流偏置，不會遇到直流偏置漂移問題。
A piezoelectric ceramic, based on the converse piezoelectric effect, was used as optical phase modulator to design a fiber differential interferometer.
基於壓電陶瓷的逆壓電傚應，採用壓電陶瓷作爲光相位調制器設計了光纖微分乾涉儀。
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.
在經過光相位調制器之後，輸出光信號的包絡保持不變，能被基站用來承載強度調制的上行信號。
