Abstract

We study the effect of strain on the properties of a one-dimensional acoustic grating: a tapered optical fiber with a periodically varying diameter. Its spectral response has a strong frequency stop band for flexural waves. Changing the tension of the fiber changes the wave velocity, and so modifies the acoustic response of the grating. The resulting tunability of the stop band over a wide frequency range is demonstrated experimentally. Furthermore, the stop band can almost disappear completely due to a strain-induced phase-matching phenomenon. Such structures are suitable as frequency-selective acoustic mirrors in acousto-optic fiber devices. (C) 2001 American Institute of Physics.
