This is really really cool, but why does it depend on TPU? Wouldn't it work with regular fiber optic? Or does it come down to economics?

It doesn't! I heavily used TPU to drive home the point that it can work with almost any light-transmitting fiber. I used PMMA optical fiber for the more fine demos.

That's great! Well done.
