1. A photonic communication platform, comprising:
a substrate;
a first photonic circuit monolithically integrated with the substrate, wherein the first photonic circuit is patterned with a first plurality of photonic modules;
a second photonic circuit monolithically integrated with the substrate, wherein the second photonic circuit is patterned with a second plurality of photonic modules;
a photonic link coupling the first photonic circuit to the second photonic circuit; and
a controller configured to arbitrate allocation of the first and second plurality of photonic modules between a first user and a second user, wherein arbitrating comprises:
causing optical isolation of the first photonic circuit from the second photonic circuit by optically interrupting the photonic link.
