Abstract
A one-dimensional grating microstructure was fabricated on a tapered optica l fiber and its acoustic properties experimentally studied. The structure c onsisted of a number of concatenated and equally spaced microtapers, fabric ated using a focused CO2 laser. Acoustic characterization of the device sho wed a strong frequency stop-band for flexural waves. Such structures are su itable as frequency-selective acoustic mirrors in acousto-optic fiber devic es.
