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 two optical transmission structures that are disposed in a fourth layer of the plurality of layers, and
• 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 an offset triter configuration.

A network of photonic elements, comprising:

• a substrate;
• and
• a plurality of photonic elements disposed on respective regions of the substrate, wherein
• each photonic element, of the plurality of photonic elements, includes a first optical transmission component, a second optical transmission component, a third optical transmission component, and a fourth optical transmission component in a stack configuration, wherein:
• the first optical transmission component includes one or more optical transmission structures,
• the second optical transmission component includes one or two optical transmission structures,
• the third optical transmission component includes one optical transmission structure,
• the fourth optical transmission component includes one or more optical transmission structures, and
• the second optical transmission component and the third optical transmission component are each disposed between the first optical transmission component and the fourth optical transmission component in the stack configuration.
