Phase reconstruction via metasurface-integrated quantum analog operation.

Caption

(a) Schematic of non-local mode selection by metasurface-integrated quantum analog operation. F^1, F^2, F^3, and F^4 are the differential operators. The green area has been designed to construct differential operators, and the blue area can be extended to construct other operators. (b) Three modes of metasurface-integrated quantum analog operation system and corresponding differential output results through non-local mode selection. (c) Theoretical phase gradient in x-direction. (d) Theoretical phase gradient in y-direction. (e) Theoretical two-dimensional (2D) phase gradient. (f) Theoretical phase distribution calculated by the 2D phase gradient.
