optical signal modulator

基本解释

A new optical fiber signal modulator based on the shear mode oscillation is designed.
设计了一种基于剪切模式振荡的光纤光调制器。
By using an unbalanced dual parallel Mach-zehnder modulator (DPMZM) followed by optical filtering, a linearized OSSB signal is obtained.
利用一种不均衡的平行调制器和光滤波器，我们得到线性化的单边带光信号。
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。
