Abstract: A method for in situ synthesis of graphene along a lengthwise direction of a waveguide applied to a photonic device includes processing an evanescent field of laser propagating in the waveguide to spread outward the waveguide, depositing a nickel thin film on a surface of the waveguide, growing graphene between a surface of the waveguide and a nickel thin film by irradiating telecommunication laser to a core of the waveguide, and removing the nickel thin film from the waveguide. Accordingly, graphene with high optical nonlinearity is in situ synthesized in the photonic device.
