A way to plastically flip a circular polariser?

Click For Summary
SUMMARY

The discussion centers on the exploration of materials or methods capable of flipping the polarization of a circular polarizer, specifically through the application of an external stimulus such as current, pressure, or heat. Participants highlight the relevance of liquid crystals, which are integral to technologies like LCDs (Liquid Crystal Displays), in achieving this polarization flip. The conversation also touches on the potential for solid-state solutions to this phenomenon, indicating a need for further research in photonic computing applications.

PREREQUISITES
  • Understanding of polarization and its applications in optics.
  • Familiarity with liquid crystal technology and its role in LCDs.
  • Knowledge of photonic computing concepts.
  • Basic principles of materials science related to elastic and plastic deformation.
NEXT STEPS
  • Research the properties and applications of liquid crystals in optical devices.
  • Investigate the mechanisms of polarization flipping in photonic materials.
  • Explore solid-state alternatives for polarization manipulation.
  • Study the effects of external stimuli (current, pressure, heat) on material properties.
USEFUL FOR

Optical engineers, materials scientists, researchers in photonic computing, and anyone interested in advanced polarization technologies.

hi, I'm currently talking about light, and I'm trying to find out if there is a material or a method that can flip a polariser's polarisation...

ie, if i apply a current, then this crystal changed from a clockwize polariser to an anti-clockwize polariser, and it is either a plastic or elastic flip

because I'm currently looking at photonic computing, and i think i saw a paper on a similar topic before... (i forgot the stimuli of the flip , so it may be pressure, heat or loads of other stuff...

thankyou

Do a search on Liquid Crystals and the Rotation of the Plane of Polarized Light. That is the technology behind LCDs (liquid crystal displays). :smile:

i face plamed myself for not able to recall this simple technology...

thanks

BTW, is there a solid version of this?
