碩士 === 國立臺灣海洋大學 === 光電科學研究所 === 103 === The nonlinear refractive indices of monolayer and bilayer graphene were measured try the spectrally-resolved two-beam coupling using a femtosecond laser. The values of the nonlinear refractive index for monolayer and bilayer graphene at 780 nm were estimated to be (5.095±0.337)×〖10〗^(-13) and (4.566±0.14)×〖10〗^(-13) m^2⁄W, respectively. The values of the nonlinear refractive index for monolayer and bilayer graphene at 800 nm wave estimated to be (1.982±0.141)×〖10〗^(-13) and n_2=(1.631±0.094)×〖10〗^(-13) m^2⁄W, respectively.
