▎ 摘　　要

NOVELTY - The filter has a Rudin-Shapiro (RS) photonic crystal provided with multiple first dielectric layers and multiple second dielectric layers. The first and second delectric layers are provided with uniform dielectrics thin sheets with high refractive indexes, where thickness of the first and second dielectric layers is 1/4 of each optical wavelength. USE - Adjustable multi-channel photon filter based on Rudin-Shapiro photonic crystal pair for use in optical technical field of optical technology. Uses include but are not limited to band-pass, band-stop, low-pass and high-pass four types. ADVANTAGE - The multi-layer structure can use the photon filter with multi-wavelength resonance optical sub-form. The number of channels can be expanded by increasing the sequence number of the Rudin-shapiro (RS) sequence. The central wavelength and transmittance of the channel can be flexibly regulated by the chemical and incident angles of the graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a sequence of the RS photonic crystal pair and graphene composite structure schematic diagram.
