Paper Abstract

In the present paper a coupled cavities filter with potential applications in photonic crystal microcircuits is studied. The analysis is based on "coupled mode theory in time" which is an approximate method that allows relatively simple derivations of optimal design parameters. Coupled cavities appear everywhere in optical circuits. In many cases they induce parasitic effects like big reflections back to the source. In other situations, if carefully designed, a device consisting of two micro cavities can act as a bandpass filter.
