DISPOSITIVO DI ACCOPPIAMENTO OTTICO E RELATIVO METODO DI SINTONIZZAZIONE

Optical coupling device (99) and method for tuning the device, the device comprising a pair of optical waveguides (1, 2) mutually optically coupled respectively at a first (3) and a second optical coupling tract (7) having main development along a longitudinal direction (100), and a first electrode (8) and a second electrode (9) electrically connected to the first optical waveguide (1 ) at longitudinally opposite sides of the first optical coupling tract (3), the method comprising applying an electric voltage difference between the first (8) and second electrode (9) to provide a passage of electric current into the first optical coupling tract (3), introducing an input optical signal, adjusting a value of the electric voltage difference to vary a ratio between optical powers of a pair of output optical signals.
