摘      要：Theoretical design of a neotype fluidic controlling sensor system based on side-polished optical fiber is *** investigations demonstrate that the higher birefringence and resonance coupling can be achieved by flexible design of the polishing shape and depth in the research *** fluidic system is beneficial to selective integration of functional *** material is integrated into the fluidic system,which can achieve a birefringence up to 6.98×10^-5,and the application of Sagnac thermometer in temperature sensing is studied,and a group of dips with different temperature sensitivities would be observed in the transmission spectra,which is about 1.6 nm/℃by ***,by introducing resonant coupling,single mode single polarization at 1310 nm is *** refractive index(RI)response of the sensing system for a low Grange of 1.39-1.37 is approximately linear,and exhibits a sensitivity of 6338 nm/*** results show that the proposed neotype fluidic controlling system can be used as a flexible polarization filter or as a potential two-parameter sensor.
