Low loss passive integrated optic interferometric sensors might successfully compete with optical fibre sensors in short path length applications such as distance measurement, force and perhaps also low performance rotation sensors. They are inherently polarization maintaining, stable, low cost and versatile. There is yet an important function which remains to be practically solved in integrated optics on passive substrates: the phaseshifting allowing a waveguide interferometer to delivering non degenerate optical power signals, ie, sine and cosine functions of the input optical phase difference. The proposed device achieving this function is a single process ion exchanged circuit on glass using a low mode number imaging waveguide caisson. The proposed configuration can be applied to all kinds of interferometers.
