▎ 摘　　要

NOVELTY - The structure has a base layer provided with a first support and a second support. A fiber core (1) is provided with an exposed section (11) that is provided with a supporting mechanism (3) i.e. u-type groove. A polished surface of a D-type optical space (111) is formed with a graphene layer (4) and provided with a contact. The graphene layer contacts with a first electrode (51) and a second electrode (52). The supporting mechanism is divided into a concave part (31) and a convex part (32). Two ends of the graphene are supported by the convex part along axial direction of the fiber core. USE - Graphene auxiliary-assisted D-type superfine optical fiber structure. ADVANTAGE - The structure obtains high nonlinear characteristic graphene, reduces insertion loss and power consumption of the device. DETAILED DESCRIPTION - The polished surface of the D-type optical space is formed with a graphene layer i.e. single-layer graphene. The first support and the second support are made of UV solidified glue. DESCRIPTION OF DRAWING(S) - The drawing shows a top perspective view of a graphene auxiliary-assisted d-type superfine optical fiber structure.
