Abstract
The authors report on a packaged LiNbO3 guided-wave network for a heterodyne receiver that combines a tunable 3-dB coupler with temperature- and wavelength insensitive optical compensators for continuous reset-free polarization transformation. A fabrication yield of 90% could be achieved by employing indium-tin-oxide-metal electrodes. Characteristic data of the device are given.
