Abstract
A study is performed of the technological processes for manufacturing fibers with short tapered regions for the new generation of optical microphones using the electrical discharge technique. The experimental use of a technique for manufacturing nanofibers with given parameters on a facility with specialized capabilities is described. Aspects of the transmission of radiation through such tapered fibers in the field of an acoustic wave are studied experimentally. The optimum parameters of tapered fibers for creating high-performance optical microphones are determined theoretically.
