Compound gain flattening filters of optical amplification include a series of filter components with spectral responses that are combined to approach a target loss spectrum. Small variations in the central wavelengths of the component responses can produce larg errors in the combined response of the compound gain flattening filter. However, the components can be divided into sub-components with balanced central wavelength deviations to achieve the desired response goals despite exhibiting otherwise detrimental wavelength deviations.

L'invention concerne des égalisateurs à gain équilibré d'amplification optique comprenant une série de composants à réponses spectrales combinées pour atteindre un spectre de perte de la cible. De petites variations des longueurs d'ondes centrales des réactions des composants peuvent provoquer des erreurs dans la réponse combinée de l'égalisateur à gain composé. Les composants peuvent, toutefois, être divisés en sous-composants et présenter des déviations de longueurs d'ondes centrales équilibrées de manière à atteindre les objectifs de réponses souhaités au lieu de présenter des déviations de longueurs d'ondes préjudiciables.
