Can information such as language, knowledge, skills, or consciousness be encoded into light and downloaded into the body?

This is a question I have been exploring through my work with light, sound, the human body, and healing.

Can information such as language, knowledge, skills, or consciousness be encoded into light and downloaded into the body?

I am currently studying photobiology and trying to understand the essence of light, how light carries information, how it interacts with matter, and how biological systems receive and transform light into signals.

I am not claiming that this is currently possible. I am looking for people who are already working on related questions, or who can help me understand what is scientifically possible, what has already been demonstrated, and where the unknown frontier begins.

I would especially like to connect with researchers working with photobiology, photochemistry, biophotonics, neuroscience, optogenetics, photomedicine, information theory, or related fields.

If you are working on something connected to this question, or know someone who is, I would love to connect and learn from you.
