Abstract :
We present a simple accurate method for the evaluation of the half-wave voltage of phase modulators at high frequency that does not require any high-speed photodiode or components or spectral analyzer. It is based on the use of a tunable unbalanced interferometer and optical mean power measurement. We report on results obtains with large bandwidth lithium niobate phase modulators.
