1. A system comprising:

  • an optical fiber having a distal fiber end and a proximal fiber end;

    an electromechanical transducer mechanically coupled to the optical fiber between the distal fiber end and the proximal fiber end, wherein the electromechanical transducer is configured to;

    apply a buckling force to the optical fiber by reducing a length of the electromechanical transducer between a distal transducer end of the electromechanical transducer and a proximal transducer end of the electromechanical transducer; and

    excite whirling of the distal fiber end by laterally deflecting the distal transducer end of the electromechanical transducer.
