Findings
Losses as low as 0.44 dB/cm in the near IR
Fibre exhibits high numerical aperture (~0.25)
Asymmetry due to 3D printing process
Abstract
Optical fibre is drawn from a dual-head 3D printer fabricated preform made of two optically transparent plastics with a high index core (NA ~ 0.25, V > 60). The asymmetry observed in the fibre arises from asymmetry in the 3D printing process. The highly multi-mode optical fibre has losses measured by cut-back as low as {\alpha} ~ 0.44 dB/cm in the near IR.
