Abstract

Cette invention concerne des techniques et un dispositif permettant d'extraire deux bandes de fréquence distinctes de la lumière reçue par une photodiode. Selon qu'ils sont émis dans une première bande de fréquence, inférieure par exemple à environ 3 MHz, ou dans une autre bande de fréquence, comprise par exemple entre 3 MHz et 50 MHz environ, les signaux sont récupérés par des circuits différents reliés l'un à la cathode, l'autre à l'anode de la photodiode.
