The influence of low-frequency acoustic vibrations on optical signals in integrated optic lithium niobate modulators is considered. It is shown that low-frequency acoustic vibrations can significantly contribute to the modulator transfer function. Characteristics of the acoustic vibrations have been observed. It is shown that these vibrations correspond to excitation of standing Lamb waves. Methods for acoustic resonance suppression have been suggested and verified.
