Foundry-manufactured, monolithically integrated multilayer silicon nitride-on-silicon photonic platforms are suitable for large-scale photonic circuits.These photonic platforms contain several wave guidelayers, and light is routed amongst the layers to create 3D photonic devices and circuits.We have realized a suite of devices in these platforms, including ultra-low-loss waveguide crossings, multilayer grating couplers, and efficient modulators. These advancements, which were initially driven by telecommunications, are leading to neurophotonic implants for brain activity mapping.
