Abstract
An electrically tunable filter based on a nanoimprinted plasmonic phase retarder and liquid crystal cell is reported. A plasmon resonance and its abrupt phase jump yield structural colors between crossed polarizers. A range of 8V is enough to access to more than half of the area covered by standard RGB filters in CIE color coordinates with a single filter. Such approach is foreseen in particular to increase the spatial resolution of display devices.
