Proca Fields in Step-index Optical Fibres

The topic of a photon mass has received justified attention over the years with strong theoretical reasoning for its existence. We derive a full description of mode solutions in step-index optical fibres on the basis of Proca's equation as a model for massive photons. The no-go theorem recently found in coaxial waveguides does not appear in the optical fibre case.
