All-optical excitonic transistor

Opt Lett. 2010 May 15;35(10):1587-9. doi: 10.1364/OL.35.001587.

Abstract

We demonstrate experimental proof of principle for all-optical excitonic transistors where light controls light by using excitons as an intermediate medium. The principle of operation of all-optical excitonic transistors is based on the control of exciton fluxes by light.
