Abstract
In this paper, we present an alternative refractive index sensing scheme based on the photonic spin Hall effect (PSHE). We find that the spin splitting induced by the PSHE shows high sensitivity to the refractive index change (RIC) around the Brewster angle.The refractive index of sample is estimated with a precision of the order of 10−5 refractive index unit (RIU) by measuring the spin splitting with weak measurements. Compared with the surface plasmon resonance sensor, this method does not require the noble metal film and keeps the same sensitivity, which is a low-cost alternative to refractive index sensing.
