Claim:
1. A light-emitting device for a wavelength division multiplex (WDM) passive optical network (PON) optical access network, the device comprising: a light source with an optical gain medium, of wavelength that is self-seeding during a go-and-return pass of light between the optical gain medium and an optical reflective component defining a laser cavity; wherein the optical reflective component is made up of an optical amplifier associated in an optical reflective connection with a polarizing device determined so that the polarization axis of the light reflected by the optical reflective component is the same as the polarization axis of the light emitted by the light source, wherein: the optical reflective connection comprises an optical loop between the optical amplifier and the polarizing device, the optical amplifier has determined polarization, and the polarizing device comprises:
