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 1.40 x 10(-13) m(2) W-1. The obtained value is similar to the n(2) value of monolayer MoS2 film measured at 2.0 mu 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.
