Abstract
A mixed frequency-based method and arrangement for characterizing an electro-optic modulator is configured to vary the tuning of a laser beam, to be modulated by the optical modulator, simultaneously with and in the same manner as the variation in frequency of the modulation signal. The effect of this dual modulation approach is a modulated laser beam, in which the frequency difference between the carrier component of the laser beam and sideband energy produced by the modulation signal is controlled so that it falls within the sensitivity range of a relatively low cost optical detector.
