Present an integrated optic eight-port 90 degrees hybrid on LiNbO3 comprising four tunable directional couplers and two phase shifters for adjusting the phases between the output ports. Measurements on the phase stability show phase fluctuations of <+or-5 degrees and a temperature dependence of approximately=15 degrees / degrees C.
