Abstract :
Regarding integrated optics devices, the variation of propagation effective index is measured using an heterodyne detection scheme. Optical phase shift is so directly transferred in the microwave frequency range allowing phase measurements using common microwave network analysers. This technique is applied to a DOS (digital optical switch) technique based switch.
