Abstract:
A network apparatus comprising an optical gain medium, a wavelength division multiplexing (WDM) filter coupled to the optical gain medium, and a Faraday Rotator Mirror (FRM) coupled to the WDM, and wherein the optical gain medium, the WDM filter, and the FRM are coupled by single mode fibers to form a self-seeded external cavity laser for a DWDM wavelength channel.
