Phase noise and spectral line shape in semiconductor lasers
TL;DR: In this article, the authors show that phase-noise spectrum is found to present a sharp peak at the same peak frequency of intensity noise spectrum, a fact which is proven to be responsible for the appearance of satellite peaks in the emission line shape.
