University spins out custom LiNbO3 firmSteve Bush The University of Southampton has spun out Stratophase, a firm set-up to produce custom lithium niobate photon manipulating crystals. Lithium niobate Lithium niobate, (LiNbO3), crystals have non-linear optical properties and can be used to multiply and divide the frequency of incident light by whole numbers. They are at the heart of most green ...

Narrow bandgap materials can control spin

BAE Systems in the US has been working with Vitesse Semiconductor and the University of Illinois to design what they claim is one of the fastest semiconductor devices ever produced. Made using an indium phosphide process, the frequency divider circuits have been clocked at 152GHz. The devices were designed by BAE Systems and manufactured in Vitesse’s indium phosphide heterojunction bipolar ...
