Claim 14:
15. A method of conducting electromagnetic radiation between layers of a multilayer photonic device, the method comprising:
receiving an input signal at an input region of the multilayer photonic device;
coupling the input signal into a multilayer stack of the multilayer photonic device, the multilayer stack comprising:
a first metastructured dispersive region disposed in a first patterned layer of the multilayer stack; and
a second metastructured dispersive region disposed in a second patterned layer of the multilayer stack and optically coupled with the first metastructured dispersive region,
wherein the first metastructured dispersive region and the second metastructured dispersive region together structure the multilayer stack to generate an output signal in response to the input signal;

generating the output signal; and
coupling the output signal into an output region of the multilayer photonic device, the output region being optically coupled with the multilayer stack to receive the output signal.
