Abstract

A theoretical and experimental investigation is reported on a novel all-fiber technique for interrogation of interferometric low-finesse Fabry-Pérot cavities. It is based on the modulation of the spectral transfer function of a wavelength-division multiplexer. Results are given when both serrodyne and sinusoidal modulation formats are considered.
