Measurement of velocity mismatch in traveling-wave electrooptic modulators
Abstract
For traveling-wave electrooptic modulators, an experimental method is described to determine the sign and magnitude of velocity mismatch between electrical and optical wave. To this end the waves are counterpropagated and frequencies yielding modulation nulls are determined. Such a measurement does also reveal dispersion of the modulator structure.
