New on DVD: Photonic Transistors

Facebook X LinkedIn Email
Daniel C. McCarthy

The ability of one electrical current or field to amplify another underlies the electronics industry's primary advantage over photonics: the transistor. By modulating electrical fields, transistors create the electronic pulses that serve as the ones and zeros of binary computing. An all-optical transistor able to transfer, attenuate or amplify energy from one wavelength to another could revolutionize application markets from switching to computing and possibly reverse electronics' dominance over photonics. Researchers at the National Institute of Advanced Industrial Science and...Read full article
