▎ 摘　　要

NOVELTY - A detection chip comprises side polishing fiber comprising core and cladding both partially polished to form polishing zone facing upward, microstrip electrode arranged on both sides of core covering non-soil zone, graphene film, polybutylene film and polymethylmethacrylate film. USE - Detection chip. ADVANTAGE - The micro wide-spectrum and high-sensitivity graphene fiber optoelectronic detecting chip has fast response speed, high detection efficiency, high stability and excellent photoelectric detection performance, and has all-fiber structure, perfectly compatible with fiber-optic communication system to overcome compatibility in production. The manufacturing process is simple, and overcomes coupling problem of the optical fiber and the waveguide structure, reduces the insertion loss, and improves the integration degree of the device.
