“…The fabrication is thus considerably simplified since these cavity mirrors are common to all the filters, while only one layer is pixelated, usually performed by reactive ion etching. Metal-Dielectric-Metal or alldielectric quarter-wave Fabry-Perot structures can be used in that case but both can only result in limited performances [5]. First, the shape of the bandpass cannot be highly selective with a single-cavity structure.…”
