▎ 摘　　要

NOVELTY - The splitter has a first waveguide area and a second waveguide area formed with a graphene waveguide interacting area, where voltage of the graphene waveguide interacting area is adjusted to change optical conductivity of a graphene layer for adjusting output power. The graphene waveguide interacting area is formed with a silicon dioxide buried active waveguide layer, an alumina layer and an electrode layer. The graphene layer is connected with an oxide layer. An upper polar plate is connected with a capacitor structure. An electrolyte layer is formed between the alumina layer and the graphene layer. USE - Broadband power beam splitter. ADVANTAGE - The splitter is small in size, has wide range of applications, and realizes reconfigurable on-chip output port changing process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a broadband power distribution method. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a broadband power beam splitter. '(Drawing includes non-English language text)'
