Investigation of Phase Modulation Sensitivity in Plastic Optical Fiber
塑料光纤相位调制灵敏度的研究

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.
