Silicon Nanoparticle Could be Heart of New Optical Transistor

The quest to transform the basis of computing from electrons to photons has been full of challenges. The aim has been to get photonic circuits to do what electronic ICs do but do it much faster—at the speed of light, achieving it has remained elusive. Researchers at ITMO University in St. Petersburg, Russia suggest that a new technique could be a big step toward photonic ICs and optical computing. It uses a single silicon nanoparticle as an optical transistor. In research published in the journal Nano Letters , the Russian scientists turned away from using nanoparticles to control the absorption of light and instead have aimed at gaining control of how light scatters off of the nanoparticle. In a press release Sergey Makarov, lead author of the study and senior researcher at the ITMO explained: Generally, researchers in this field are focused on designing nanoscale all-opt...
