Embodiment 1

[0018] The invention provides a device for generating circularly polarized light, such as figure 1 As shown, it includes a substrate 1 , a noble metal micro-nano structure array layer 2 , a lead lanthanum zirconate titanate transparent ceramic part 3 , a first force applying part 4 and a second force applying part 5 . The noble metal micro-nano structure array layer 2 is placed on the substrate 1 . The material of the base 1 is a transparent material. Specifically, the material of the substrate 1 is silicon dioxide. The material of the noble metal micro-nano structure array layer 2 is gold or silver. The lead lanthanum zirconate titanate transparent ceramic part 3 is placed in the middle of the noble metal micro-nano structure array layer 2 . The first force application part 4 and the second force application part 5 are placed on the noble metal micro-nano structure array layer 2 and fixedly connected to opposite sides of the lead lanthanum zirconate titanate transparent ce...

Embodiment 2

[0021] On the basis of Example 1, the thickness of the L-shaped noble metal micro-nano structure is less than 100 nanometers. That is to say, the electrons in the L-shaped noble metal micro-nanostructure mainly vibrate in the horizontal direction, rather than in the vertical or oblique direction. In this way, it is simple to adjust the phase difference of two mutually perpendicular vibration components in the L-shaped noble metal micro-nano structure.

[0022] Furthermore, the L-shaped noble metal micro-nanostructure is partially embedded in the substrate 1, so as to avoid the movement of the L-shaped noble metal micro-nanostructure when the lead lanthanum zirconate titanate transparent ceramic layer 3 undergoes a slight displacement under pressure. .

[0023] Furthermore, the two arms of the L-shaped noble metal micro-nanostructure are the same. In this way, the two perpendicular electric vectors with a phase difference vibrate with the same intensity, so that stronger circ...

Description

technical field [0001] The invention relates to the field of circularly polarized light preparation, in particular to a device for generating circularly polarized light. Background technique [0002] When circularly polarized light with different polarization interacts with chiral substances, it shows different responses. Therefore, the preparation of circularly polarized light is the basis of chiral optics. Traditional devices that generate circularly polarized light cannot be adjusted. When preparing circularly polarized light with different polarizations, the device needs to be remade, which is costly. Contents of the invention [0003] In order to solve the above problems, the present invention provides a device for generating circularly polarized light, including a substrate, a noble metal micro-nano structure array layer, a lead lanthanum zirconate titanate transparent ceramic part, a first force application part, a second force application part, a precious metal T...
