Hi there,

I wonder if anyone heard or read anything about glass where one can control its polarization electronically. Or such that you can switch polarization on and off. Tried to google but all it gives references to polarized glass. Maybe I am using wrong term for such thing?

Thanks in advance,
Ildar

Welcome to the PF.

Use the search term "liquid crystal", or you can just look it up on wikipedia. That's the technology used in liquid crystal displays (LCDs).
 

1. What is electronically controlled polarization of glass?

Electronically controlled polarization of glass is a process in which the alignment of molecules within a glass material is altered by applying an electric field. This results in changes in the refractive index and optical properties of the glass.

2. How does electronically controlled polarization work?

Electronically controlled polarization works by applying an electric field to a glass material, causing the molecules within the material to become polarized and align in a specific direction. This changes the way light passes through the glass and can alter its optical properties.

3. What are the applications of electronically controlled polarization of glass?

Electronically controlled polarization of glass has various applications in optics and photonics, including in optical switches, modulators, and waveguides. It is also used in liquid crystal displays (LCDs), optical communication systems, and other technologies that require precise control of light.

4. What are the benefits of electronically controlled polarization over other methods?

Compared to other methods of controlling the properties of glass, such as mechanical or thermal methods, electronically controlled polarization offers faster response times, higher precision, and greater flexibility in controlling the properties of the glass material.

5. Are there any limitations or challenges associated with electronically controlled polarization of glass?

One limitation of electronically controlled polarization is that it is not suitable for all types of glass materials. Additionally, the process requires a constant supply of electricity, which may not be feasible in certain applications. There are also challenges in maintaining the stability and uniformity of the polarization over time.
