▎ 摘　　要

NOVELTY - The filter has five first dielectric layers and three second dielectrical layers that are arranged in order from incident direction to emergent direction, where thicknesses of the first dielectric layer and the second dieelectric layer are respectively 1/4 of optical wavelength corresponding to a refractive index. A graphene single layer is embedded in a boundary between two adjacent first and second dieelectric layers. A transverse magnetic wave is vertically incident from a center of an incident side of an adjustable dual-channel photon filter. USE - Adjustable dual-channel photon filter for use in a multi-channel communication system. Uses include but are not limited to a band-pass, band-stop, low-pass and high-pass four types. ADVANTAGE - The filter adjusts transmittance and central frequency of a filter channel.
