Title: Fiber acoustic waveguide and system

Abstract: A fiber acoustic waveguide comprising a single crystal fiber and a single ystal film deposited on the outer elongated surface of the single crystal fiber, wherein the single crystal film has a higher velocity of propagation than the single crystal fiber. The fiber acoustic waveguide has a delay that is directly proportional to its length, whereupon fixed lengths of the waveguide provided fixed delay. A fiber acoustic waveguide system is provided by connecting one end of the waveguide to driving transducer means for converting an electrical signal to an acoustic signal, and the other end of the waveguide to pickup transducing means for converting the transported acoustic signal from the waveguide back into an electrical signal.
