Massimo Moccia Bouncing to and fro across the core at close to 90o to the fibre axis, the acoustic waves form optical-phonon-like modes with a flat dispersion curve and a distinct cutoff frequency Omegaa. In this paper, we present the study of the acousto-optic behavior of underwater-acoustic sensors constituted by fiber Bragg gratings (FBGs) coated by ring-shaped overlays. Via full-wave numerical simulations, we study the complex opto-acousto-mechanical interaction among an incident acoustic wave traveling in water, the optical fiber surrounded by the ring shaped coating, and the FBG inscribed An acousto-optic modulator, also called a Bragg cell or an acousto-optic deflector, uses the acousto-optic effect to diffract and shift the frequency of light using sound waves. They are used in lasers for Q-switching, telecommunications for signal modulation, and in spectroscopy for frequency control. A piezoelectric transducer is attached to a material such as glass. An oscillating electric signal drives the transducer to vibrate, which creates sound waves in the material.

The intrinsic high frequency and wide bandwidth associated both to the opto-acoustic source and to the interferometric acousto-optic element could open a way towards a “virtual biopsy”. “Virtual biopsy” is perspective to provide the physicians the possibility of studying the nature and health condition of small portions of living tissue “in situ” by using ultrasounds.

Thus the acoustical waves generated by the absorbed light were transferred to an elongation of the fiber. The cell was operated at one of its resonances. 2011-09-26 Opto-Acoustic Fiber Sensor Opto-Acoustic Fiber Sensor Munir, Q.; Weber, H.

The acoustic waves created An opto-electronic oscillator based on guided acoustic wave Brillouin scattering in a photonic crystal fiber (PCF) stimulated by a light wave in 1 μm band is proposed and demonstrated. A short length of a homemade PCF stimulated by relatively low pump power leads to strong coupling between the pump and probe waves. The oscillation is realized in a feedback loop, in which the acoustic wave The rates of opto-acoustic coupling for the various transitions are given by κ η ζ ξ j where η, ζ, and ξ are combinations of R, M, s, and f. The derivation of the model, together with detailed definitions of all these parameters is available in the supplementary material. 23 23.
