ABSTRACT:
Devices for modulating light signals. A modulator includes a rolled optical fiber cable having a preset tensile stress along the longitudinal axis thereof, a coating layer applied to the rolled optical cable, and at least one piezo acoustic transducer secured to the coating layer. The piezo acoustic transducer is operative to generate a sound wave that modulates a frequency of a light signal passing through the rolled optical fiber cable.
