Ring-resonator-based optical mirrors are analyzed and their characteristics numerically evaluated. The mirrors are optimized to provide high reflection in a relatively narrow band. A design procedure that relates the required coupling to the bandwidth (BW) and reflection coefficient is presented. The effect of waveguide loss on the transmission and reflection performance is computed. Group delay and dispersion under the influence of loss and circuit-parameter variations are also treated.
