Apparatuses and methods for photonic communication and photonic addressing

Abstract

Apparatuses and methods for photonic communication and photonic addressing are disclosed herein. An example apparatus includes a photonic source layer that provides a plurality of photonic sources, each at a different wavelength, a plurality of second layers, and a third layer. Each of the plurality of second layers may be associated with a respective wavelength, and each of the plurality of second layers may include photonic filters tuned to their respective wavelength, a photonic modulator, and a photonic detector. The third layer may include a plurality of photonic circuits, with each of the plurality of photonic circuits associated with a respective second layer of the plurality of second layers. Additionally, each of the plurality of photonic circuits may include a photonic filter tuned to a respective wavelength associated with a respective second layer, a photonic detector and a photonic modulator. Modulated and unmodulated photonic signals may be provided from the second layers to the third layer and from the third layer to the second layers, where the respective wavelengths of the photonic signals acts like an address for each of the plurality of second layers.
