Abstract

The invention discloses a one-way transmission device for linearly and circularly polarized light based on a wave plate, an experimental device and a using method, the one-way transmission device forthe linearly polarized light is composed of a half-wave plate and a polarizing film, and the half-wave plate and the polarizing film are installed on the same supporting column. The optical axis of the half-wave plate and the optical axis of the polarizing film are sequentially arranged on the same straight line, and the included angle between the optical axis of the half-wave plate and the incident plane is 45 degrees. The circular polarization light source is composed of two quarter-wave plates and a polarizing film, the two quarter-wave plates and the polarizing film are installed on the same supporting column, the centers of the two quarter-wave plates and the center of the polarizing film are located on the same straight line, the polarizing film is arranged between the two quarter-wave plates, and the included angle between the optical axis of the first quarter-wave plate and the incident plane is 45 degrees. The device is high in average transmissivity contrast ratio of forwardand reverse transmission, capable of meeting one-way transmission of linearly polarized light and circularly polarized light, simple in structure and free of additional excitation.

Description

technical field [0001] The invention relates to the technical field of electromagnetic wave transmission regulation, in particular to a wave plate-based unidirectional transmission device for linearly and circularly polarized light, an experimental device and a use method. Background technique [0002] One-way transmission means that there is a big difference in the transmittance of light incident from the front and back of the structure, and it is an irreversible technology for light waves. With the development of information technology, people pay more and more attention to information security. Therefore, one-way transmission has broad application prospects in optical communication systems and information processing, and it is particularly important to realize one-way transmission of electromagnetic waves. [0003] The traditional method to achieve unidirectional transmission is to use magneto-optical materials and nonlinear materials. However, magneto-optic materials re...
