Optical filters play a critical role in optoelectronics, high-speed chips, and display applications. To achieve higher resolution, it is required to miniaturize the optical filters. Conventional color filters consist of pigment or organic dyes which degrade over time. Hence, many alternative designs have been implemented that rely on structural color via surface plasmon polaritons (SPPs) or guided mode resonance (GMR) that achieve chemical stability and high resolution. However, most miniaturized color pixels reported up to date have suffered from degraded filtering performance when the number of array elements decreases We propose an optical pixel design that does not rely on SPPs or GMR, but on the scattering cancellation via a metal-semiconductor-metal hybrid nanostructure array. Such hybrid nanostructure can transmit certain wavelengths of visible light even with a single array element without any degradation in spectral response. By arranging individual elements of the same type into an array, we can create color pixels that exhibit wide gamut and highly efficient (>40 %) transmission. Furthermore, by effectively combining different elements into a single array, we can allow multi-pass transmission. As such, our proposed design for color pixels offers intuitive degrees of freedom for displaying multispectral and high definition colors in displays and optoelectronic applications
