<p>An optical switch comprises at least a first input optical guide (1) having a first beam exit termination (11) and a first and second output optical guides (3,4) respectively having first and second beam entrance terminations (31,41), and a movable reflecting element (6), operatively associated with said exit termination and entrance terminations, movable between a first position and a second position, the first position causing an optical beam (14) exiting from said exit termination to be directed towards the first entrance termination, the second position causing said optical beam to be directed towards the second entrance termination. A normal direction to each of said exit termination and entrance terminations forms a first angle ( alpha 1), different from 0 DEG , with an optical axis (12,32,42) of the respective guide, said first angle depending on optical properties of the guides and of an optical transmissive medium between the exit termination and entrance terminations and being such that back-reflected beams inside the guides are attenuated with respect to a guide termination perpendicular to the optical axes of the guides. The optical switch is suitable to be integrated in a substrate, with integrated guides converging to a recess formed in the substrate and adapted to movably house the reflecting element. <IMAGE></p> |
