Optical brain scanner goes where other brain scanners can't

Scientists have advanced a brain-scanning technology that tracks what the brain is doing by shining dozens of tiny LED lights on the head. This new generation of neuroimaging compares favorably to other approaches but avoids ...

Ultra-fast photodetector and terahertz generator

Photodetectors made from graphene can process and conduct light signals as well as electric signals extremely fast. Within picoseconds the optical stimulation of graphene generates a photocurrent. Until now, none of the available ...
