METHOD FOR SYNTHESIS OF GRAPHENE ALONG WAVEGUIDES IN SITU PHOTONICS DEVICE INCLUDING GRAPHENE OBTAINED USING THE METHOD

摘要

A method of synthesizing in situ graphene along a longitudinal direction of a waveguide applied to an optical element includes: processing an evanescent field of a laser traveling through the waveguide to spread out of the waveguide; Irradiating a communication laser to the core portion of the waveguide to grow graphene between the surface of the waveguide and the nickel thin film; And removing the nickel thin film from the waveguide. Accordingly, graphene having high optical nonlinearity can be directly synthesized in the optical device.
