(Phys.org)—"We believe wireless communications should be as reliable as lighting." That is a company motto of startup PureVLC (Visible Light Communication), which aims to connect the two—communications and light. They ...
(Phys.org)—While today's smart phones, tablets, and other small electronic devices rely on electrical data connections, in the future they may use optical connections in order to become even faster and smaller. Photonic ...
Gallium nitride (GaN) is a highly promising material for a wide range of optical and high-power electronic devices, which can be fabricated by dry etching with plasmas. However, the plasma-induced defects and surface residues ...
