Abstract

In one particular example, a molecular-analysis and diagnostic method involves an apparatus including a photonic mirror device having: outer opposing-end sections each including a set of one or more nanoblocks arranged to form a pre-tapering or padding section: a cavity section including differently-dimensioned interspersed nanoblocks of a length dimension d and of a perturbation dimension Ad; and situated between the opposing ends and the cavity section, first and second sets of three or more nanoblocks forming tapered sections (e.g., via a line that tracks with a polynomial-like function). At least the respective tapered sections and the cavity section cooperate to support guided-mode resonance for a metasurface pixel (“GMR pixel”) by containing light and optimally minimize energy losses due to scattering of light, in response to light being directed towards an optical sensor via the GMR pixel.
