Novel tunable optical filter employing a fiber loop mirror for synthesis applications in WDM
A novel optical filter employing a fiber loop mirror within an amplified ring resonator is presented. The fiber loop mirror allows tuning by changing the coupling factor of a coupler. The device can be used as a building ...
Synthesis of Optical Filters Using Sagnac Interferometer in Ring Resonator
We propose a new synthesis method for the implementation of infinite impulse response filters, using a Sagnac interferometer within a ring resonator. This structure permits the synthesis of second-order optical functions ...
