Hollow core fiber? Total internal reflection requires the core to be a higher index of refraction than the cladding, so I wonder how that works!

Turns out, it functions differently. Instead of total internal refraction it has to rely on weird physics like photonic crystals. The pictures are absolutely wild.

Fascinating; thanks for the links. I wonder how the splicing process works for that.
