Abstract
(EN)
The invention is an optoelectronic device for coupling between an external optical wave (10) and a local optical wave (16, 18, 20). The local wave is supported by a multiplicity of electrodes (12), and a structure associated with the electrodes. The multiplicity of electrodes are spaced in a substantially regular pattern and are adapted for two functions. First, the electrodes resonantly couple between the external wave and the local wave. Second, the electrodes allow a potential difference between adjacent electrodes. In one embodiment, the multiplicity of electrodes are substantially planar, metal, interdigitated electrodes including first finger and second fingers (22, 24). The electrodes are further adapted to allow a potential difference between the first fingers and the second fingers. In addition, the structure associated with the electrodes is a substantially planar silicon substrate (14) contacting the electrodes. The local wave is a surface plasmon (16) supported by the metal electrodes and silicon substrate. The index of refraction of the silicon may be altered by varying the potential difference across the first and second fingers of the electrodes. The optoelectronic coupler may be configured to modulate or detect incident light.

Dispositif optoélectronique destiné au couplage d'une onde optique externe (10) et d'une onde optique locale (16, 18, 20). L'onde locale est portée par une série d'électrodes (12) et une structure associée à ces électrodes. Les électrodes de cette série sont espacées selon un schéma relativement régulier et sont conçues pour deux fonctions. Tout d'abord, elles établissent un couplage résonant entre les ondes externes et l'onde locale. Deuxièmement, des électrodes contiguës autorisent une différence de potentiel entre elles. Selon l'un des modes de réalisation, les électrodes sont essentiellement planes, en métal et interdigitées, comprenant un premier et un deuxième doigts (22, 24). Elles sont en outre conçues pour autoriser une différence de potentiel entre le premier et le deuxième doigt. En outre, la structure associée aux électrodes est essentiellement un substrat plan de silicium (14) au contact de celles-ci. L'onde locale est un plasmon de surface (16), supporté par les électrodes métalliques et le substrat de silicium. On peut modifier l'indice de réfraction du silicium en modifiant la différence de potentiel entre les premiers doigts des électrodes et les seconds. Le coupleur optoélectronique peut être configuré de manière à moduler ou capter une lumière incidente.
