Abstract
We present dual-cavity based reflective structural color filters that can produce RGB additive colors featuring high purity and high efficiency. We decided to design a filter with a new wavelength by combining two classical MDM structure Fabry-Perot cavities with different resonant wavelength. A cavity medium with high refractive index leads to angle-invariant performance up to 50˚. Moreover, only deposition is involved so that the device can be easily scaled over a large area. The described approach may provide new avenues for various applications, such as reflective displays and surface coatings for decoration and solar cells.
