Paper Abstract

We present an all-fiber filter with symmetric forward and feedback lattice structures. Using the proposed filter, Gaussian-like spectra can be equalized in the maximally flat sense while the output power is maximized. As an illustrative example, the proposed filter is designed to flatten the output spectrum of a superluminescence light-emitting Diode (SLED). Compared to existing filters, the proposed filter achieved better performance in experiments.
