Abstract

The fano-resonance biosensor is formed through the phase variation of microcavity- resonator-coupled Mach-Zehnder interferometers. After windowed Fourier transform, the biological phase sensitivity could be effectively enhanced and theoretically demonstrate the limit of detection as 10^-7 refractive-index-units.
