Laser Excitation of Torsional Vibrations in Optical Microfibers

Abstract

Comparative analysis of mechanisms of the laser excitation of torsional vibration modes in optical microfibers shows that special attention should be devoted to the Sadovsky effect manifested in polarization-anisotropic optical microfibers. Estimations of the efficiency of this mechanism for the excitation of torsional vibrations and polarization modulation in the proposed types of anisotropic quartz microfibers shows the possibility of creating new types of polarization elements—optically controlled fiber polarization devices and sensitive elements for resonance fiber-optic sensors.
