Tiny Black Holes Enable a New Type of Photodetector for High Speed Data (IMAGE)
Caption
Photodetectors for optical to electronic signal conversion usually make use of efficient, but expensive materials other than silicon. A new approach uses tapered holes in silicon to trap photons and send them sideways through a silicon wafer, boosting efficiency. The approach allows high-efficiency, high-speed photodetectors that could be cheaper and more efficient for use in data centers.
