Frenet-Serret analysis of helical Bloch modes in N-fold rotationally symmetric rings of coupled spiralling optical waveguides

Abstract

Frenet-Serret theory is generalised to the case of a chiral ring of N coupled birefringent cores. The dispersion and polarisation of the helical Bloch modes are derived, for the first time properly including torsion effects.
