Abstract

The invention relates to a light source capable of generating circularly polarized light through utilization of electricity. The light source comprises a substrate layer, wherein a first metal layer is set on the substrate layer; a quantum well layer is set on the first metal layer; a second metal layer is set on the quantum well layer; and an array composed of a plurality of chiral metal holes isset on the second metal layer. According to the light source capable of generating circularly polarized light through utilization of electricity, the circularly polarized light can be directly generated; through utilization of the chiral metal holes, a phase of the linearly polarized light is deviated and after the light is superposed, the circularly polarized light is formed; the circularly polarized light does not need to be generated through utilization of a biaxial crystal; and the generated circularly polarized light can be adjusted through adjustment of a voltage loaded to the quantum well layer. The light source is convenient. Time is reduced.

Description

technical field [0001] The invention belongs to the technical field of circularly polarized light sources, and in particular relates to a light source for electrogenerating circularly polarized light. Background technique [0002] Circularly polarized light is a special case of elliptically polarized light, which is produced by rotating the endpoint of the electric vector to trace a circular trajectory. When the propagation directions are the same, the vibration directions are perpendicular to each other and the phase difference is constant as After the two plane polarized lights of π are superimposed, the circularly polarized light whose electric vector changes regularly can be synthesized. [0003] In the prior art, the relatively common methods for generating circularly polarized light are through Babinet compensators and Sorey compensators. [0004] The Babinet compensator is a composite prism composed of two quartz wedge-shaped plates whose optical axes are perpendic...
