Automatic gain control and dynamic equalization of erbium doped optical amplifiers in wavelength multiplexing networks

摘要

A system and method for controlling alignment of laser center wavelengths and filter passband center wavelengths in optical amplifiers for purposes of providing automatic gain control and eliminating unwanted noise. The system and method exploits a wavelength-locked loop servo-control circuit and methodology that enables real time mutual alignment of a laser pump signal having a peaked spectrum function including a center wavelength and a wavelength selective device such as an optical filter implementing a peaked passband function including a center wavelength in an optical amplifier.
