In order to generate oscillating polarisation, the researchers bend the laser with a nail (left). Thus, the active material is no longer symmetrical and becomes birefringent. Generally speaking, the more strongly a laser is bent, the faster the oscillation. Credit: RUBIN, photo: Schirdewahn
RUB engineers have developed a new concept for accelerating data transfer in server farms. To this end, the team at the Chair of Photonics and Terahertz Technology applies a quantum-mechanical variable, i.e. the spin. RUBIN, the science magazine published by the Ruhr-Universität Bochum, reports on how researchers optimise so-called spin lasers for data transfer.
