Experimental Investigations on Lasers FM and AM Noise

Abstract

Different 1550 nm fibered lasers are compared versus their performances in terms of frequency (FM) noise and amplitude (AM) noise. The noise spectral density is spread over six to height decades for the FM noise and three to four decades for the AM noise, depending on the frequency offset. The lasers featuring the best FM noise performance are generally the worst versus the AM noise performance, although some compromises can be found.
