Abstract
The letter presents two novel methods, based on Fabry-Perot interference, for the characterisation of passive and active waveguide devices. Loss measurements have been made on passive devices using a distributed feedback laser as a frequency-tunable source. Simultaneous measurement of phase shift and loss are obtained for a phase modulator by using the electro-optic effect.
