Abstract

We demonstrate and optimize a microfluidic refractive index sensor with ultra-high sensitivity based on an acoustic grating in a solid core photonic bandgap fiber. The sensitivity of the acoustic grating's resonance is 17 900 nm/RIU which corresponds to smallest detectable changes in refractive index of 8.4×10^-6.
