Abstract

The nonlinear refractive index of large area monolayer molybdenum disulfide (MoS2) thin film at the 1,550 nm wavelength band is determined using time-resolved z-scan technique. MoS2 exhibits positive nonlinear phase shift with a large nonlinear refractive index, n 2 value of 1. 4 0 × 1 0 − 1 3 m 2 W − 1 . The obtained value is similar to the n 2 value of monolayer MoS2 film measured at 2.0 μ m, and is approximately five and seven orders of magnitude larger than silicon and common bulk dielectrics. The large n 2 indicates that MoS2 can be used as nonlinear refractive 2D material for photonics applications operating in the 1,550 nm optical telecommunications wavelength band.
