The principle of an integrated optic component providing four optical signals in quadrature is presented. Such an interferometric element has been fabricated by ion -exchange in glass. The effect of various parameters on the quadrature condition have been studied: length of the mixing section, temperature, polarisation. Losses have been characterised. A possible use of this device is illustrated.
