Power/Performance Bits: Oct. 9


Topological insulator waveguides Engineers at the University of Pennsylvania and Polytechnic University of Milan applied topological insulators to photonic chips to make reconfigurable waveguides. In topological insulators, charged particles can flow freely on the material's edges but can't pass through the interior. For photonics, topological insulators with edges that could be redefined m... » read more

Manufacturing Bits: Oct. 29


Diamond chips The optical transistor, which transports photons, holds great promise. Photons are not only faster than electrons, but they have less crosstalk. But optical transistors are also expensive and difficult to produce. In a possible breakthrough, the ICFO-Institute of Photonic Sciences has demonstrated a “nano-size” diamond that can act as an efficient optical switch. Researche... » read more
