主  题:fiber bandgap characteristic 

摘      要:A novel fluid sensing system based on side-polished optical fiber(SPOF)is proposed,which realizes the fluid replaceability and effective refractive index(RI)sensing *** investigations demonstrate that the photonic bandgap effect can be obtained if the RI of liquid is higher than that of substrate material in the wavelength range *** relationship between bandgap edge wavelength and RI is studied *** SPOF with a depth of 57μm is used in the experiment to realize the construction of the fluid *** filling three different liquids,the result shows that the wavelength of the bandgap edge has a red shift with RI increased,which is nearly linear in the RI range of 1.56—1.6 with a sensitivity about 5543.64 nm/*** proposed sensing system can be flexibly applied to the field of fluid characteristic sensing such as biochemical solution characteristic detections.
