First Circularly Polarized Light Detector On A Silicon Chip

Invention of the first integrated circularly polarized light detector on a silicon chip opens the door for development of small, portable sensors that could expand the use of polarized light for drug screening, surveillance, optical communications and quantum computing, among other potential applications. The new detector was developed by a…Continue readingFirst Circularly Polarized Light Detector On A Silicon Chip

Physicists Create Exotic State: Could Lead To New Sensors And Optical Devices

The Dirac cone, named after British physicist Paul Dirac, started as a concept in particle and high-energy physics and has recently became important in research in condensed matter physics and material science. It has since been found to describe aspects of graphene, a two dimensional form of carbon, suggesting the…Continue readingPhysicists Create Exotic State: Could Lead To New Sensors And Optical Devices

Sea Sapphire’s Magic Trick Unmasked

The tiny ocean creatures known as sea sapphires perform a sort of magic trick as they swim- one second they appear in iridescent shades of blue, purple or green, and the next they may turn invisible (at least the blue ones turn completely transparent). How do they get their bright…Continue readingSea Sapphire’s Magic Trick Unmasked
