Light circular polarization modulator

Abstract

The invention discloses a light circular-polarization modulator, including a light input coupler, a light output coupler and at least a birefringent regulable crystal, where the crystal can change the shape or major axis orientation of its refractive index ellipsoid under the action of electric, magnetic, temperature and light fields or force, by this characteristic, able to modulate levorotary and dextral circularly-polarized lights, thus realizing the convenient and practical effect, and mainly applied to chiral substance detection and identification, communication coding and optical teaching.

AI Technical Summary

Benefits of technology

This technology allows us to create an opaque device that lets through only one type of electromagnetic radiation at once without affecting its other types of waves like radio signals transmitted by satellites. It uses this property to control how much energy it emits from different directions while still allowing them to pass freely between two states called state A and B. By controllably changing these properties, we have made possible new ways to make things look more natural when looking around with their surroundings (like being able to see if there are any objects). Additionally, they could detect even small amounts of materials such as drugs or chemical agents within our environment easily.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving how well known linearly polarizers work with both left-right handed circularlypolarized lights (LHCP) and nonlinear ones such as birefringence (B), achromatic aberrator(ACOA).
