A way to plastically flip a circular polariser?

[1832vin]

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).

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

thanks

BTW, is there a solid version of this?
