Moore’s Law is ending, opening up exciting possibilities for computers with new architectures and form factors. The research in the Poon Department will be centered on 3D multi-technology microsystems. A major theme of our research will be devices and systems that bring nanotechnology into brains, so that we may “bring brains into nanotechnology.” Our goal is to advance computing and neuro-science/medicine.

Our main research directions will be multi-technology implantable devices that stimulate and record neurons, integrated photonic devices for 3D micro-displays, and highly energy-efficient phase-change material based electronic and optoelectronic devices. These devices can be considered as different forms of brain interfaces and computing components. The core physical technology to be developed will be foundry-fabricated visible light integrated photonic platforms in silicon. Foundry fabrication enables a path toward mass-manufacturing and broad dissemination of our research. 

Our research program unites the forefronts of integrated photonics, micro-system integration, neurobiology, and computing. It will build upon our multi-disciplinary and international collaborations with semiconductor foundries, neurobiologists, engineers, computer scientists, and other researchers.
