▎ 摘　　要

NOVELTY - The memory has a graphene single layer embedded in a dielectric layer to form a three-layer structure, where thickness of the first dielectrical layer and the second dieelectric layer is optical wavelengths of each optical wavelength, and thickness of the graphene single layers are respectively uniform dielectrics with high refractive index and low refractive indexes. A memory body of the photon crystal based on lutin-sipinolinois realizes a low threshold optical bi-stable state. The memory body obtains upper and lower threshold values of the lower threshold value corresponding to the writing and reading decision threshold of the optical memory. USE - Optical memory based on rubutin-Xanpino photonic crystal for use in all-optical communication. Uses include but are not limited to optical domain, transmission, relay, timing, amplifying and shaping. ADVANTAGE - The memory enhances nonlinear effect of graphene, reduces threshold value of the optical bistable state, so that it can be applied to the optical memory. The writing and reading decision threshold of optical memory, reading the decision threshold value, and the interval between the write decision threshold and the read decision threshold can be flexibly controlled by the chemical potential and incident wavelength of the graphene single layer, so as to realize low threshold optical bi-stable state. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an optical memory based on rubutin-Xanpino photonic crystal.
