The Response of Optical Fibres to Gravitational Waves
preprintposted on 2023-01-11, 22:14 authored by Thomas Mieling
The response of optical fibre modes to plane gravitational waves of low frequency is computed. By solving perturbatively the Maxwell equations for step-index optical fibres in a gravitational wave background and implementing appropriate boundary conditions to describe single-mode fibres, explicit formulae for the perturbations of the phase and the polarisation of the fibre modes are obtained.
