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.
