The invention discloses a miniature wide-spectrum and high-sensitivity
graphene fiber photoelectric detection
chip. The miniature wide-spectrum and high-sensitivity
graphene fiber photoelectric detection
chip comprises a side
polishing fiber,
microstrip electrodes, a
graphene thin film, a PB thin film and a PMMA thin film, wherein the side
polishing fiber comprises a fiber core and a
coating layer, the
coating layer and the fiber core are partially polished to form a
polishing region, the polishing region of the side polishing fiber faces upwards, the
microstrip electrodes are arranged at twosides of the fiber core and cover non-polishing regions, and the PMMA thin film, the PB thin film and the graphene thin film sequentially cover upper surfaces of the
microstrip electrodes from top tobottom. The
chip has the characteristics of
rapid response speed, high detection efficiency, high stability and excellent photoelectric
detection performance; an all-
fiber structure is employed and isperfectly compatible with a fiber communication
system, and the problem of compatibility in production is solved; and the chip is directly fabricated on the fiber, the fabrication process is simple,
mass production is facilitated, the problem of
coupling of the fiber and a
waveguide structure is also solved, the
insertion loss is reduced, and the device integration is improved.
