Abstract :
Theoretical and experimental results are presented on single-mode 
-junction switching devices in Ti-diffused LiNbO3 waveguides. The operation of these devices relies on a redistribution, by means of the elcctrooptic effect, of the power in the input waveguide before it is transmitted to the output waveguides of the -junction. Measured performance is shown to be predicted satisfactorily by a theoretical model of a -junction in homogeneous, planar waveguide. Transmission losses of less than 1 dB and extinction ratios of about 15 dB have been obtained in a device with a junction half-angle of 0.57°.
