Paper Abstract

We demonstrate an electro-optic phase modulator based demodulation system for acoustic frequency modulated optical signals. The system is free from polarisation fading and is capable of retrieving high frequency signals, ultimately limited by the time of flight of the interferometer itself. Digital interrogation method is based on the Carré algorithm and does not require fine tuning of the introduced phase and is suitable for simultaneous phase retrieval at multiple wavelengths without the need for correction transfer filters.
