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.

Claim (Index 18):
The ultrafast optical switching device according to  claim 17 , wherein further comprises at least one component of a first channel and a second channel to generate different continuous wave lasers, a modulator to embed a signal on the laser through modulation, a tunable filter to tune center wavelength with the laser to reduce noise, a directional coupler to couple the lasers, an amplifier to respectively amplify the intensity of the laser, and a polarization controller (PC) to control polarization of the laser.
