Abstract
An apparatus includes an optical amplifier waveguide and an optical reflector located to reflect back some light received at or near a first end of the optical amplifier waveguide. The apparatus also includes another optical waveguide having a first end located to receive light at or near a second end of the optical amplifier waveguide, and the another optical waveguide having a sequence of optical ring resonators optically connected there along with each of the optical ring resonators being configured to have a different free spectral range. A system and a method are also included.
