Abstract

A digital optical switching device (1) has a longitudinal axis (9) and comprises a substrate (2); a first, a second and a third waveguide (3-5), connected by a connecting waveguide (10), the second and third waveguides (4, 5) having a first and second refractive index respectively, and forming two alternative branches for carrying the light from and/or towards the connecting waveguide; electrodes (6-8) associated with at least one of the second and third waveguides (4, 5) and capable of forming an electrical field region in which at least one of the first and second refractive indices can be varied as a function of a potential difference applied to the electrodes; and in which there is a first longitudinal region (I) in which the connecting waveguide (10) forms a first angle (υ1), a second longitudinal region (II) consisting of a first longitudinal area (II-A), in which the second and third waveguides (4, 5) comprise respective first sections (4a, 5a) forming between them a second angle (υ2) which is different from the first angle (υ1), and a second longitudinal area (II-B) in which the second and third waveguides (4, 5) comprise respective second sections (4b, 5b) forming between them a third angle (υ3) which is different from the second angle (υ2).
