Stable transmission of 12 OAM states in air-core fiber

We demonstrate modally pure propagation over a record number (12) of modes in an optical fiber. An air-core fiber enables this by supporting OAM states. We achieve mode purities >10dB over 2m for all states and >20dB after 1km for a 2 state subset.
