Abstract
A reflective light-emitting device is provided for a WDM PON optical access network. The device includes a light source with an optical gain medium. The light-emitting device includes a light source with an optical gain medium, of wavelength that is self-seeding during a go-and-return passage of light between the optical gain medium and an optical reflective component defining the laser cavity. The optical reflective component is made up of an optical amplifier associated reflective optical connection to a polarizing device so that the polarization axis of the reflected light is the same as the polarization axis of the emitted light.
