Data Sheet Gain Flattening Filter Chips Bookham Gain Flattening Filters (GFF) leverage the proprietary Advanced Energetic Deposition (AED) process to produce the industry’s lowest error GFF. The AED process features state-of-the-art layer thickness control enabling custom gain profiles to be closely replicated over multiple production runs. Low loss custom designs can be made for erbium doped fiber amplifier (EDFA) bands in the C and L bands. Designs for Raman-based amplification are also available. Bookham has developed software design tools to synthesize custom gain profiles and assess their manufacturing robustness. When you work with Bookham on your GFF design, you will have an expert design team on your side.
