Photonic element and network of photonic elements

A photonic element, comprising:

• a substrate;
• a plurality of layers disposed in a stack configuration in a first direction on the substrate;
• and
• a first optical transmission component, a second optical transmission component, a third optical transmission component, and a fourth optical transmission component, wherein:
• the first optical transmission component includes two optical transmission structures that are disposed in a first layer of the plurality of layers,
• the second optical transmission component includes two optical transmission structures that are disposed in a second layer of the plurality of layers,
• the third optical transmission component includes one optical transmission structure that is disposed in a third layer of the plurality of layers,
• the fourth optical transmission component includes one optical transmission structure that is disposed in a fourth layer of the plurality of layers,
• the second layer and the third layer are each disposed between the first layer and the fourth layer in the stack configuration, and
• the two optical transmission structures of the second optical transmission component and the one optical transmission structure of the third optical transmission component are arranged in a triter configuration.

A network of photonic elements, comprising:

• a substrate;
• a first photonic element that comprises four first optical transmission components in a first stack configuration in a first direction on a first region of the substrate;
• and
• a second photonic element that comprises four second optical transmission components in a second stack configuration in the first direction on a second region of the substrate, wherein:
• the four first optical transmission components include two middle first optical transmission components that each include a pair of optical transmission structures,
• the pairs of optical transmission structures of the two middle first optical transmission components are arranged in a first quarter configuration,
• the four second optical transmission components include two middle second optical transmission components that each include a pair of optical transmission structures, and
• the pairs of optical transmission structures of the two middle second optical transmission components are arranged in a second quarter configuration.
