摘要
本文研制了一种单模光纤(Single Mode Fiber,SMF)和光子晶体光纤(Photonic Crystal Fiber,PCF)熔接点形成Mach-Zehnder干涉仪(MZI),它是通过将单模光纤和光子晶体光纤进行偏执熔接和塌陷熔接形成的MZI。研究了此类传感器传输光谱随外界折射率的变化关系。实验结果表明,在1.5367~1.5783折射率变化范围内,该传感器的折射率测量灵敏度可达82.09nm/RIU。
In this paper, a Mach-Zehnder interferometer( MZI) is fabricated by the fusion point of single mode fiber( SMF) and photonic crystal fiber( PCF). The single mode fiber and photon Crystal fiber for paranoid welding and collapse welding MZI. The relationship between the transmission spectra of these sensors and the refractive index of the outside is studied. Experimental results show that the refractive index of the sensor can reach 82. 09 nm/RIU within the range of refractive index of 1. 5367 ~ 1. 5783.
