We report a polarization-dependent optical sensor based on reduced graphene oxide (rGO) and demonstrate its applications in detecting refractive indices. The s-polarized absorption of the rGO under the conditions of total internal reflection is unique over the range of 400–1100 nm and its amplitude is sensitive to the media that is in contact with the rGO. We have conducted detailed calculations and experiments to optimize the performance of the sensor. The sensitivity of the optical sensor is <inline-formula> <tex-math notation="LaTeX">$3.10~\Delta $ </tex-math></inline-formula> R/RIU and its resolution is <inline-formula> <tex-math notation="LaTeX">$9.7\times 10 ^{-4}$ </tex-math></inline-formula> RIU.
