Fabrication of rGO-GO Long Period Fiber Grating Using Laser Reduction Method
A laser-reduction technique is investigated to fabricate a novel long period fiber grating (LPFG), whose period is a section of graphene oxide (GO) and reduced graphene oxide (rGO) films on a side polished fiber. Raman spectra, X-ray diffraction, and Fourier transform infrared spectra show that a CW...

| Summary: | A laser-reduction technique is investigated to fabricate a novel long period fiber grating (LPFG), whose period is a section of graphene oxide (GO) and reduced graphene oxide (rGO) films on a side polished fiber. Raman spectra, X-ray diffraction, and Fourier transform infrared spectra show that a CW 405 nm laser with low power of only 84 mW is sufficient to fabricate this LPFG by laser-reducing the GO film to rGO film. It is demonstrated that the dip extinction ratio of 15.3 dB can be achieved for such rGO-GO LPFG with a 500 <italic>μ</italic>m period. In addition, it is found that the extinction ratio, full width at half maximum and resonant wavelength of the dip can be optically tuned by the length of LPFG. The work opens a way to implement novel fiber devices based on rGO-GO micro/nanostructure. |
