Abstract
A system and method for improving optical signal gain efficiencies of semiconductor optical amplifier devices. The system and method exploits a wavelength-locked loop servo-control circuit and methodology that enables real time mutual alignment of the center wavelength of an optical signal having a peaked spectrum function and transmitted through the semiconductor optical amplifier, and a center wavelength of a wavelength selective device such as an optical filter implementing a peaked passband function in an optical system. The wavelength-locked loop servo-control circuit and methodology may be further exploited to control various types of modulation applied to the optical signals transmitted in optical systems.
