Abstract

The invention provides an intelligent optical power distribution device based on a meta-surface material. The intelligent optical power distribution device is characterized by comprising a meta-surface array structure formed by arranging nano-brick units and capable of focusing orthogonal linear polarization lights irradiating in major-minor axis directions of the nano-brick units on different locations so as to perform optical power distribution, wherein each nano-brick unit is composed of a dielectric substrate and a nano-brick formed on the dielectric substrate, and the dielectric substrateand the nano-brick are in sub-wavelength size. The intelligent optical power distribution device provided by the invention performs phase operation on the orthogonal optical wave in the major-minor axis directions of the nano-bricks by utilizing polarization independent feature for transmitting the phase meta-surface material, and the orthogonal optical waves in the major-minor axis directions ofthe nano-bricks can be respectively focused on different locations, thereby realizing efficient optical power distribution.

Description

technical field [0001] The invention belongs to the field of micro-nano optics, in particular to an intelligent optical power distribution device based on metasurface materials. [0002] technical background [0003] The optical power splitter is a passive optical device that divides the optical signal into multiple outputs. Current optical power splitters include coupling splitters and branch splitters. Coupling splitter is a device that couples optical signals in a special coupling area and redistributes them. The splitting ratio of this device is difficult to precisely control, and the manufacturing process is complicated and the cost is high. The bifurcated optical path directly divides the optical signal into multiple output devices. The splitting ratio is controlled by adjusting the branching angle, and it is difficult to realize real-time splitting ratio adjustment for a certain kind of fixed branching optical path device. Therefore, new method breakthroughs and in...
