Abstract :
The performance of resonantly enhanced LiNbO3 traveling wave optical modulators is investigated. High-frequency performance of broad band velocity matched LiNbO3 modulators with low half-wave voltages is shown to be relatively independent of termination. A resonant enhancement technique involving external line stretching of the length of the nonactive section of the modulator is proposed and demonstrated at low-frequencies. An accurate model is developed to facilitate design of resonantly enhanced optical modulators
