The name of the game in optical metasurfaces is shortening the wavelengths of light. This yields devices that can manipulate light for information processing and also reduce the bulk of the devices based on traditional optics. Metasurfaces have been pretty good at offering small, flat features, but the integrated metallic resonators they use to filter light according →

Physicists have succeeded in confirming one of the theoretical aspects of quantum physics: Subatomic objects switch between particle and wave states when observed, while remaining in a dual state beforehand. In the bizarre world of quantum mechanics, events rippling back in time may not seem that much stranger than things like “spooky action at a →

Electrons move fast, especially within an atom. But they have their limits, and those limits might put a top speed on future optoelectronic circuits. http://spectrum.ieee.org/tech-talk/semiconductors/optoelectronics/fastest-light-pulses-show-that-electrons-react-slowly-to-light Posted from WordPress for Android →
