Reconfigurable dual-channel dropping filters based on a self-coupled resonator Sagnac interferometer.

We report a reconfigurable dual-mode resonator-based dual-channel dropping filter. The dual dropping channels are generated within a free spectral range (FSR) via the interference between the electromagnetically induced transparency (EIT)-like and electromagnetically induced absorption (EIA)-like resonances despite only one resonator used. The reconfiguration of the dual channels enabling the truly on/off switching mechanism is realized, and the output modes resembling the add/drop/neutral states are provided. The compact, reliable, flexible, versatile, and extendable filter has profound implications for wavelength division multiplexing (WDM) applications in optical interconnection networks.
