Abstract :
Frequency mixing effects introduced by the photodetectors in optical fibre interferometer systems have been examined experimentally. Thin film PVF2 strips attached to the single-mode-fibre interferometer arms served as voltage-driven phase modulators. These mixing effects, while possibly limiting the dynamic range of fibre sensor systems, may be used for frequency multiplexing.
