Abstract

The invention discloses a light field regulation and control sensor and a use method thereof. The sensor comprises a glass prism, a photonic crystal coupling layer and an air layer, the glass prism is fixedly connected with one surface of the photonic crystal coupling layer, and no air exists between the glass prism and the photonic crystal coupling layer; the air layer is positioned on the other opposite surface of the photonic crystal coupling layer; the use method comprises the following steps: S1, injecting a horizontally polarized Gaussian beam into the glass prism from air, and carrying out total reflection at the interface of the glass prism and the photonic crystal coupling layer to obtain a reflected beam; and S2, applying a magnetic field in a direction perpendicular to the incident plane of the Gaussian beam to obtain a reflected beam of moving GH displacement, and completing regulation and control of the beam. According to the method, the problem that the GH displacement is small in an existing method for regulating and enhancing the GH displacement is solved.

Description

technical field [0001] The invention relates to a refractive index sensor, in particular to a light field control sensor and a use method thereof. Background technique [0002] The GH displacement is a small displacement along the interface direction between the actual reflected beam and the position predicted by geometric optics when the incident light is totally reflected at the interface of the medium. Various high-sensitivity sensors, filters, optical switches and other optical devices can be designed and fabricated by enhancing the GH shift. [0003] Surface plasmon resonance (SPR) is a phenomenon of electron oscillation and evanescent wave coupling at the interface between metal and dielectric. SPR sensing technology is based on the above phenomena to detect and analyze certain substances on the metal surface, and the change of the received SPR optical signal is caused by checking the change of the refractive index of the sample. [0004] At present, the main method ...
