Claim:
1. An apparatus, comprising: first and second photonic paths; a first layer at least coupled to the first photonic path, the first layer configured to provide a plurality of photonic signals to the first photonic path, wherein each of the plurality of photonic signals has a different wavelength; a plurality of second layers coupled to the first and second photonic paths, wherein each second layer of the plurality of second layers is associated with a photonic signal of the plurality of photonic signals based on a respective wavelength, wherein each second layer of the plurality of second layers comprises: a third layer including a plurality of photonic circuits, the third layer coupled to the first and second photonic paths, each photonic circuit of the plurality of photonic circuits associated with a photonic signal of the plurality of photonic signals based on a respective wavelength such that there is a photonic circuit associated with each second layer of the plurality of second layers, wherein each photonic circuit of the plurality of photonic circuits is configured to receive the plurality of photonic signals, filter a photonic signal of a respective wavelength from the plurality of photonic signals, and provide the filtered photonic signal of the respective wavelength to the second photonic path.
