Cameras are becoming smaller in order to meet the need for increased resolution and smaller form factors, such as demand for compact devices. This miniaturization requires smaller pixels and a redesign of traditional color filters. Many color filters are based on traditional absorptive dyes which are susceptible to cross talk as pixel size decreases and fade over time.
In this application note, we explore two alternative color filter types: plasmonic based color filters built from thin metal films, and Dielectric color filters built from dielectric materials.
