Design of a robust thin-film interference filter for erbium-doped fiber amplifier gain equalization
Gain-flattening filters (GFFs) are key wavelength division multiplexing components in fiber-optics telecommunications.

| Summary: | Gain-flattening filters (GFFs) are key wavelength division multiplexing components in fiber-optics telecommunications. Challenging issues in the design of thin-film GFFs were recently the subject of a contest organized at the 2001 Conference on Optical Interference Coatings. The interest and main difficulty of the proposed problem was to minimize the sensitivity of a GFF to simulated fabrication errors. A high-yield solution and its design philosophy are described. The approach used to control the filter robustness is explained and illustrated by numerical results. |
