Abstract
A vertical tri-color sensor having vertically stacked blue, green, and red pixels detects at least blue and green components of incident light by converting the blue and green components to surface plasmons.
Claims14
A color sensor array comprising:
- a first corrugated metal/dielectric interface that converts a first color component of incident light to first surface plasmons;
- a second corrugated metal/dielectric interface that converts a second color component of the incident light to second surface plasmons;
- and
- a third corrugated metal/dielectric interface that converts a third color component of the incident light to third surface plasmons,
- wherein the first corrugated metal/dielectric interface is stacked above and covers the second corrugated metal/dielectric interface and the second corrugated metal/dielectric interface is stacked above and covers the third corrugated metal/dielectric interface.
