Title
(EN) INTEGRATED OPTICAL SWITCH
(FR) COMMUTATEUR OPTIQUE INTÉGRÉ
Abstract
(EN)
Integrated optical switch formed in and on a semiconductor substrate, comprising a photoconductive body (PC) comprising a first end (1) configured to receive an electrical input signal and a second end (2) configured to provide an electrical output signal, the photoconductive body (PC) having an electrically conductive state activated by the presence of an optical signal (SO) and an electrically blocked state activated by the absence of the optical signal (SO), wherein the direction from the first end to the second end defines a longitudinal direction (D3), and the photoconductive body has a cross section orthogonal to the longitudinal direction (D3) gradually decreasing in the longitudinal direction (D3) from the first end (1) to the second end (2).
(FR)
Commutateur optique intégré réalisé dans et sur un substrat semi-conducteur, comportant un corps photoconducteur (PC) comprenant une première extrémité (1) configurée pour recevoir un signal électrique d'entrée et une deuxième extrémité (2) configurée pour délivrer un signal électrique de sortie, le corps photoconducteur (PC) ayant un état électriquement passant activé par la présence d'un signal optique (SO) et un état électriquement bloqué activé par l'absence du signal optique (SO), dans lequel la direction allant de la première extrémité vers la deuxième extrémité définit une direction longitudinale (D3), et le corps photoconducteur a une section transversale orthogonale à la direction longitudinale (D3) diminuant progressivement selon la direction longitudinale (D3) depuis la première extrémité (1) vers la deuxième extrémité (2).
