Abstract
Techniques for implementing a dual array waveguide filter for a wavelength division multiplexed passive optical network (WDM-PON) are disclosed. In one particular exemplary embodiment, the techniques may be realized as an apparatus for implementing a dual waveguide filter for a wavelength division multiplexed passive optical network (WDM-PON). The apparatus may include a first light source configured to output a first broadband optical signal for generating a downstream optical signal. The apparatus may also include a second light source configured to output a second broadband optical signal for generating an upstream optical signal. The apparatus may further include a dual array waveguide filter having a first optical transmission path and a second optical transmission path, wherein the first optical transmission path is configured to spectrally slice the first broadband optical signal and the second optical transmission path is configured to demultiplex the upstream optical signal.
