We propose and numerically demonstrate subtractive color filters (SCFs) based on a plasmonic metasurface including coaxial aperture geometry working in the visible range. The Proposed designs involve ...
Plasmonic color filters employing a single optically-thick nanostructured metal layer have recently generated considerable interest as an alternative to colorant-based color filtering technologies, ...
Photometers or light meters are radiometers that include a filter and photodiode and responds based on the average human eye: the CIE 1924 luminosity function V λ. However, the light sensitive diode ...
