▎ 摘　　要

NOVELTY - The device has an oscillator orderly arranged along a light path, an optical parametric amplifier, a beam splitter and a lens. The oscillator generates a certain wavelength of ultra-fast light. The ultra-fast light generates two beams of wavelength that are adjusted by the optical parametric amplifier. The detection light and the pump light are combined into a beam of synthetic light beam after passing through the beam splitting mirror and irradiated on a graphene sample through the lens. A collecting light path collects a harmonic signal generated by the graphene sample. USE - Full light control graphene nonlinear optical effect device for a two-dimensional material system in an optical switch and an optical communication field. ADVANTAGE - The device has high modulation efficiency, low energy loss, simple manufacturing technique and wide application prospect in field of optical switch and optical communication. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for full light control method of graphene nonlinear optical effect. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene nonlinear optical effect full light control device for two-dimensional material system.
