▎ 摘　　要

NOVELTY - The amplifier has an optical amplifier main body arranged with a hollow photonic crystal fiber (1) and a light filter (3). An inner wall of the hollow photonic crystal fiber is arranged with a hollow core region and an air core layer. The air core layer is arranged with multiple film dispersing graphene quantum dots (2). The air core layer is covered on the light filter. The hollow core photon crystal fiber is coated on an inner wall of the fiber micro-graphene quantum dots. The hollow core photon crystal fiber is arranged with an air core along a radial direction. USE - Graphene quantum dot optical amplifier. ADVANTAGE - The amplifier is directly inserted into an optical system by utilizing the hollow photonic crystal fiber so as reduce optical transmission loss and improve light conversion efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene quantum dot optical amplifier.
