Photonic crystal fiber surface plasmon resonance effect based on supercontinuum source

A method of using the air-hole collapsed technology of photonic crystal fiber(PCF) to make surface plasmon resonance (SPR) sensors has been proposed. The air-hole completely collapsed PCF-SPR sensor model has been established and simulated. All-fibered wavelength-detection PCF-SPR sensors were constructed, and a supercontinuum source was used to do the correlated experiments. When air is the ambient medium to be tested, the measured resonance wavelength is 465 nm, which accords with the simulation.
