Abstract
A multispectral pixel structure is provided that includes a plurality of stacked cavity arrangements for emitting or detecting a plurality of specified wavelengths, wherein each stacked cavity arrangement having a photoactive layer for spectral emission or detection of one of the specified wavelengths. The photoactive layer is positioned within a resonant cavity stack and the resonant cavity stack being positioned between two adjacent mirror stacks. A plurality of coupling-matching layers are positioned between one or more of the stack mirror arrangements for controlling optical phase and coupling strength between emitted or incident light and resonant modes in each of the stacked cavity arrangements.
