Abstract :
An integrated optic eight-port 90°-hybrid has been realized on LiNbO3. The phase pattern was tuned electro-optically. The packaged unit showed the desired phase relations of 0°, 90°, 180° and 270° between the respective output ports with excellent longterm stability. The phase fluctuations are less than ±5° and the temperature induced phase drift is 15°/°C
