Wavelength Self-Managed Optical WDM Source Using Polarization-Multiplexed Fabry–PÉrot Laser Diodes

We propose and demonstrate a novel wavelength self-managed optical source for access networks. By polarization multiplexing with two Fabry-Pe/spl acute/rot laser diodes, we can largely reduce wavelength and polarization dependence on the injected amplified spontaneous emission (ASE) light. The worst case power penalty incurred by the wavelength detuning can be decreased within 1 dB. We can obtain not only increased signal power and signal-to-noise ratio but also widened operation range. Even though polarized ASE light is used, data transmission is possible using the proposed source. Therefore, the proposed source is very practical to use in low-cost optical wavelength-division-multiplexing access networks.
