▎ 摘　　要

NOVELTY - The method involves directly depositing dielectric medium material (2) on an end surface of an oblique wedge splitting optical fiber (1). Graphene (3) is paved on a surface of the dielectric medium material. UV graphene near infrared absorption process is optimized. A visible light wave band absorptivity of UV light in an UV range is determined. An inclined angle of the oblique wedge splitting optical fiber is determined. Thickness of the dielectric medium material is measured. A central wavelength of the UV light is calculated. A desired UV near infrared absorption value is determined based on the thickness of the dielectric material. USE - Method for improving graphene UV near infrared absorptivity. ADVANTAGE - The method enables improving UV near infrared absorption effect. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a graphene.
