1. A modulator arrangement for acoustically modulating optical radiation, the modulator arrangement comprising:

  • an optical waveguide formed from a flexible material;

    a vibrator element for generating acoustic vibrations; and

    a coupling arrangement for releasably coupling the vibrator element to a portion of the waveguide,the coupling arrangement including a first coupling member secured to the portion of the waveguide at an attachment point, and a second coupling member secured to the vibrator element,wherein the second coupling member is releasably retained in an acoustically coupled position with the first coupling member, andwherein the first coupling member has a substantially rigid portion for retaining the shape of the portion of the waveguide when the second coupling member is released from the first coupling member.
