Observation of Imbert–Fedorov shift in monolayer MoS2 via quantum weak measurement

We report the experimental evidence of the Imbert–Fedorov (IF) shift in monolayer M o S 2 for a fundamental Gaussian beam. Using Jones vector formalism, we have shown a novel, to the best of our knowledge, pathway to apply the quantum weak measurement technique for easy and accurate determination of the IF shift. We have revealed the dependence of IF shift over a large range of angles of incidence along with the mode of polarization of the incident light. Our experimental findings via the weak value amplification scheme are in good agreement with the theoretical analysis. The present method is a general one and can also be implemented for other materials to observe such tiny transverse shifts.
