Author(s) from Durham


An approach using simple analytical theory has been developed for the design of multilayered spectral optical filters based on coupled microcavities. The method has been applied to find the parameters of the optimal structure, providing a near square-shaped transmission band. The case of normal and oblique incident light has been considered. It is shown that the situation corresponding to the weak coupling-strong coupling threshold for coupled cavity modes is optimal for achieving a square-shaped transmission band.
