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.

Sumario: 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. Simple equations to design the device are included.
