Abstract

This paper describes an idea of creating a liquid analyte sensor based on a one-dimensional (1D) photonic crystal - dielectric mirror - integrated on the optical fiber end face and creating a resonant cavity with the reversed structure. This geometry produces the evident resonances within the photonic band gap spectral region which are sensitive to refractive index changes inside the resonant cavity. The main idea is to use this arrangement as a sensor in Lab-on-a-chip (LOC) device with two single mode optical fibers (SMFs). An inlet and outlet is proposed for different liquid analyte delivery and in-situ monitoring of the refractive index change of the analyte.
