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

RLC Circuit as a Damped Oscillator
Consider a series RLC circuit. Here, the presence of resistance in the circuit leads to energy loss due to joule heating in the resistance. Therefore, the total electromagnetic energy in the circuit is no longer constant and decreases with time. Since the magnitude of charge, current, and potential difference continuously decreases, their oscillations are said to be damped. This is...
