ABSTRACT:
A method of modulating light incident to a semiconductor body comprising the steps of: coupling the incident light to the surface plasmon polariton mode at an interface of the semiconductor body; and selectively altering the absorption of the incident light by the semiconductor body so as to decouple the incident light from the surface plasmon polariton mode. The absorption can be selectively altered by establishing a quantum confined optical absorption region within the semiconductor body, and effecting a Stark shift of the quantum confined optical absorption region.
