Abstract

The comments given here refer to the two excellent and complete papers by Foster (see ibid., vol.40, no.7, p.884, 2004 and ibid., vol.40, no.9, p.1283, 2004). After closely studying the papers, we have found a couple of issues that require comments in order to understand and use the model. Despite this, one should honor the achievements in the papers in which Foster establishes an accurate analytical model for a DFB fiber laser. The comments relate to a gain parameter and the noise arising from pump power fluctuations and something that affects the noise equations, which we believe to be a small misprint
