Abstract

Viene proposto un commutatore (14, 15) ottico, il cui segnale di ingresso (S1, S2) ottico viene addotto alla guida d'onda di ingresso (55, 56) insieme ad una luce di pompaggio (P1, P2). La guida d'onda di uscita (51, 52, 53, 54) e/o la guida d'onda direttrice (38, 39, 40, 41) sono drogate con un drogante che provoca un'amplificazione della luce di segnale.(Figura 1).
