Title: Optical automatic gain control based on stable, non-absorbing optical hardlimiters

Abstract: Optical automatic gain control (AGC) is accomplished using stable,non-absorbing optical hard limiters and various optical logic gatesderived therefrom. The AGC mechanism preserves the ratios between signallevels and provides an adjustable amount of gain.
