Abstract

The invention discloses a light-operated optical switch which comprises a magnetic base, a graphene sheet with a notch and a driving light source, the graphene sheet is arranged on the magnetic base in a suspended mode under the action of a magnetic field, and the graphene sheet is provided with the driving light source used for driving the graphene sheet to move in the circumferential direction.The advantages of the light-operated optical switch are that: by controlling light irradiation and changing the deflection of the magnetic polarization direction of the graphene sheet, the graphene sheet rotates under the action of a magnetic field such that the regulated light passes through or does not pass through the notch to realize the modulation of the controlled light, and the light-operated optical switch can realize the simultaneous modulation from ultraviolet to infrared spectrum ranges, and is high in modulation speed and modulation efficiency.

Description

technical field [0001] The invention relates to the technical field of light control, in particular to a light control light switch. Background technique [0002] High-speed optically controlled optical switches have a wide range of applications in optical integrated circuits, optical computing, all-optical circuits, and optical interconnections. Traditional light-controlled optical switches mainly use the nonlinear effect of optical materials, that is, use control light with strong light intensity to change the refractive index of optical materials, thereby adjusting the transmittance or reflectance of the controlled light, thereby realizing the control of light to light. . This method has a very high modulation speed, but requires a strong control of light intensity, and can only work near a specific wavelength, and the modulation wavelength range is narrow. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a l...
