Wide tunable filters using a recirculating delay line with multi-reflections
A ring resonator with multiple reflections as a tunable filter is proposed and analyzed in this paper. A coupler and two identical Bragg gratings are used to implement the internal reflections so an active filter with a wide tuning range controlled through a coupler coupling constant is derived. Sim...
