Researchers at the National Institute of Standards and Technology (NIST) have identified a class of silicon photonic sensors that could be effective in high-radiation environments because of their ability to withstand high radiation doses. Results from tests performed by the team indicate the durability of such devices under harsh conditions and suggest that these sensors could be customized to measure radiation doses in both industrial applications and clinical radiotherapy. The researchers exposed two kinds of silicon photonic sensors — silicon ring resonators and Bragg...Read full articleRelated content from Photonics MediaARTICLESLight-Scattering Phenomenon Could Improve Optical CommunicationsA phenomenon observed in a miniature light-scattering system composed of an ultrathin layer of silicon nitride on a chip could lead to improved optical communications and sensors.
