Nanooptics: Photons pushed together
Michel Orrit1
Abstract
Photons don't interact well with each other, which is a real headache for researchers developing all-optical transistors for computing applications. But a single molecule can mediate photon–photon affairs.
Transistors in computers generally modify electrical signals (source currents) using other electrical signals (gate voltages). The nonlinear interactions in and between networks of transistors thus underpin all electronic computing.
