| Abstract: | Present an integrated optic eight-port 90° 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 <±5° and a temperature dependence of ≈15°/°C |
