Abstract

An optical filter twice filters an optical signal. The optical filter includes a first optical waveguide, an elliptical optical resonator, and a second optical waveguide. The optical signal is coupled from an input/output port of the optical filter which is a port of the first optical waveguide. A portion of the optical signal is coupled through and filtered by the elliptical optical resonator. The filtered optical signal is emitted from another port of the optical filter which is a port of the second optical waveguide. A reflector reflects the filtered optical signal back into the other port. The filtered optical signal is coupled through and filtered by the elliptical optical resonator to the input / output port. A twice filtered optical signal is emitted from the input / output port.
