optical phase modulator

基本解釋

The optical phase modulator does not suffer from the bias drifting problem as it does not need DC bias.
由于光相位調(diào)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.
基于壓電陶瓷的逆壓電效應(yīng)，采用壓電陶瓷作為光相位調(diào)制器設(shè)計了光纖微分干涉儀。
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(jīng)過光相位調(diào)制器之后，輸出光信號的包絡(luò)保持不變，能被基站用來承載強度調(diào)制的上行信號。
