We provide additional details on the bend perturbation calculation necessitated by labelling errors in Fig. 3(a) of Optica 2, 267 (2015) [CrossRef]  , and provide one citation missing from the original manuscript.

Figures (1)

Fig. E1.
Fig. E1. Coupling coefficient, in dB scale, due to bend perturbations in an air core fiber according to (E3), for multiple bend angles, θ. For each angle, the coefficients rapidly decrease as the Fourier series order increases, in agreement with the intuition that angular momentum should be conserved.
