▎ 摘　　要

NOVELTY - Method for manufacturing micro-ring resonator of composite planar graphene oxide film comprises e.g. thinning standard single-mode optical fiber through melting and tapering to obtain double-end tapered optical fiber, knotting the double end, using a three-dimensional control platform, dispersing nano-sheet in graphene oxide dispersion liquid in the mixed solution drop of the micro ring resonance, evaporating ethanol solvent in mixed solution liquid drop and forming a layer of graphene oxide plane film on the surface of micro ring reinforcement, accessing the micro round resonance of the primarily dried composite surface-shaped graphene oxide membrane between the broadband light source and spectrometer, improving the extinction ratio of the transmission spectrum, and the micro-ring resonator of the micro-ring resonator of the composite surface-shaped graphene oxide film is encapsulated on the glass slide by ultraviolet glue, placing in a sealed box for drying for a period of time. USE - Method for manufacturing micro-ring resonator of composite planar graphene oxide film of mode-locked optical fiber laser used in fields of quantum optics, fiber parametric oscillator and Raman microscope. ADVANTAGE - The micro-ring resonator composite planar graphene oxide film of the mode-locked optical fiber laser can realize high stability, low self-starting locking pump power, high coherence, high damage threshold value of the laser output. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a micro-ring resonator of composite planar graphene oxide film; and a mode-locked fiber laser of micro-ring resonator composite planar graphene oxide film. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a micro-ring resonator of composite planar graphene oxide film.
