Embodiment Construction
[0027] The specific implementation of the intelligent optical power distribution device based on the metasurface material involved in the present invention will be described in detail below with reference to the accompanying drawings.
[0028]
[0029] Such as figure 1 with 2 As shown, the intelligent optical power distribution device 10 based on metasurface material provided in this embodiment is a metasurface array structure formed by arranging a plurality of silicon nanobrick units 11 . The silicon nano-brick unit 11 is composed of a dielectric substrate 11a and a silicon nano-brick 11b etched thereon. Both the dielectric substrate 11a and the silicon nano-brick 11b are in the shape of a cuboid, the length, width and height of the dielectric substrate 11a and the silicon nano-brick 11b are all sub-wavelength scales, and the working surface of the dielectric substrate 11a is a square. The surfaces of the dielectric substrate 11a and the silicon nano-bricks 11b etched the...
