Nature inspires CMOS colour sensor

Nature inspires CMOS colour sensor

An aluminium surface grating can add colour selectivity to CMOS chips, without separate colour filters, claims a team of US researchers.

The grating works by surface plasmon – where photons interact with a wave of electrons. Colour selection, and focussing, comes from interference between the plasmonic grating and the photodetector’s…
