Plasmonic Color Filter Array with High Color Purity for CMOS Image Sensors

Plasmonic Color Filter Array with High Color Purity for CMOS Image Sensors

We demonstrate the multiband color filtering of a standard RGB color and a complementary CMY color by a plasmonic color filter, composed of concentric corrugated metallic thin film rings. The surface plasmon resonance is excited by the periodic corrugation, and the coupled light is transmitted throu...
