Lighting up the brain: Wafer-scale integrated photonics for implantable neural interfaces

Optical actuation and imaging of genetically targeted neuron types have emerged as powerful tools to map neural circuits. In partnership with a commercial silicon photonics foundry, we have developed photonic integrated circuit platforms operating in the visible spectrum. We are using this technology to realize implantable neural probes that enable unique multifunctional interfaces to the brain for neuroscience research.
