I study theoretically the responsivity of optical modulators. For the case of a linear response, by using perturbation theory I find an upper bound imposed on the responsivity. For the case of a two-mode modulator I find a lower bound imposed on the optical path required for achieving full modulation when the maximum birefringence strength is given.
