MEASUREMENT OF THE FREQUENCY-RESPONSE INDUCED BY ELECTROSTRICTION IN OPTICAL FIBERS

Accurate measurements of the frequency response of the nonlinear refra ctive index induced by the combined effects of Kerr nonlinearity with electrostrictional excitation of acoustic waves in optical fibers are presented. A detailed experimental investigation of both standard (zer o-dispersion wavelength, lambda(0) approximate to 1.31 mu m) and dispe rsion-shifted (lambda(0) = 1.55 mu m) single-mode fibers showed the pr esence of several resonant peaks induced by the electrostrictive nonli nearity in the fiber structure. This investigation has provided better insight into the frequency behavior of the electrostriction-induced a coustic waves in optical fibers. (C) 1997 Optical Society of America.
