Optical Encryption Research Sources

Optical encryption is a way of securing digital data like a locked door. Instead of a physical key, though, it uses light. Optical encryption and spatial light modulators have become an important part of data security. By leveraging the power of light to protect data, it provides encryption that is far superior to standard methods. A device called a spatial light modulator wraps the light into a specific shape. That wrapped light is then used to encrypt the data, so it can only be decrypted with the correct light pattern. It’s like giving a secret code to only a few individuals who can then open the door. Researchers are advancing the technology of optical encryption with the aid of spatial light modulators, leading the way to a future of secure data.
