Frequency conversion of vortex states by chiral forward Brillouin scattering in twisted photonic crystal fibre
Xinglin Zeng, Philip St. J. Russell, Birgit Stiller
Optical vortex states-higher optical modes with helical phase progression and carrying orbital angular momentum-have been explored to increase the flexibility and capacity of optic…

Frenet-Serret analysis of helical Bloch modes in N-fold rotationally symmetric rings of coupled spiralling optical waveguides
Yang Chen, Philip St. J. Russell
The behavior of electromagnetic waves in chirally twisted structures is a topic of enduring interest, dating back at least to the invention in the 1940s of the microwave travelling…
