Embodiment 1
[0023] (1) Using the finite difference time domain method (FDTD) to simulate the figure 1 The shape of the sub-wavelength circular aperture array 4 of the two-dimensional cold atomic surface optical lattice 5 can be realized, and the drawing software is used to design and draw the drawing.
[0024] (2) Coating a layer of noble metal (such as silver) thin film on the flat silicon wafer by magnetron sputtering method, and then use the femtosecond laser processing system to process periodic circular apertures on the noble metal thin film, and process the figure 1 Subwavelength circular aperture arrays in 4 .
[0025] (3) Use the bracket to place figure 1 The subwavelength circular aperture array 4 in the medium is placed horizontally, the installation is fixed in place, and the noble metal thin film part faces upward.
[0026] (4) figure 1 Medium light source system 1 consists of figure 2 It consists of laser 8, chopper 9, focusing lens 10 and optical fiber 11. Adjust the l...
