摘要：

The special character of a PCF which is used as a gas or liquid sensor is discussed. The field distribution is analyzed when the solid core PCF is injected with different medium that has different relative dielectric constant (or refractive index). And the experiential formulas of the relation between refractive index of some kinds of liquid and their concentration are given, in order to measure the concentration of the relative liquid. At the same time, the effect of propagation constant on PCF sensor character is also discussed. Furthermore, the photonic band-gap (PBG) of PCF (PBG-PCF) is calculated at different medium relative dielectric constant, when it is injected with different medium. That is the principle basis for this kind of PCF sensors. © Tianjin University of Technology 2007.
