摘要
研究了压电涂层PMMA纤芯塑料光纤中的相位调制.射频信号通过对光纤外层的压电涂层作用,使纤芯中产生应变,从而对光纤中的光信号进行相位调制.数值计算结果表明,与传统的石英光纤相比,PMMA塑料光纤的相位调制的灵敏度要高数十倍以上.
The phase modulation within piezoelectric coating PMMA core plastic optical fiber (POF) is demonstrated. RF signals induce strains within fiber core due to electric mechanic effects in piezoelectric coating, thus the phase of optical signals in fiber is modulated. Compared with conventional glass fiber, PMMA core POF has a phase modulation sensitivity of more than ten times larger.
