Optical carrier modulator by surface plasmons, based semiconductor materials

摘要

Optical carrier modulator by surface plasmons, semiconductor based materials, quecomprende: - a set of semiconductor layers comprising a guiding structure (21, 22, 23) for an incident optical wave introduced into said guiding structure, ensuring that unconfinamiento asymmetric guiding structure of said optical wave; - a metal layer called top which forms a Schottky contact type (26) with said decapas set semiconducting and intended to receive, in particular, said optical wave guided by said set of capassemiconductoras thereby enabling the generation of a plasmon wave surface in interfazmetal / semiconductor; and - means adapted to modulate the optical index of said set of semiconductor layers on electric elcontacto Schottky thereby creating a modulation of the optical wave reflected in dichainterfaz.
