Welcome to the HIP Lab!
We are the Heterogeneously Integrated Photonics (HIP) Lab in the Department of Electrical & Computer Engineering at North Carolina State University in Raleigh, NC. Our research is multidisciplinary and aims to advance integrated photonics in computational, communication, and sensing systems research - this entails exploring novel heterogeneous semiconductor photonic devices, large-scale photonic integrated circuits, architectures/algorithms, and developing a deeper understanding of neuromorphic/quantum inspired computation that lies closer to nature.
We are currently searching for passionate/talented/motivated students and scholars to come join us in pushing the state-of-the-art in integrated photonics. If interested please contact Prof. Cheung at scheung3 [at] ncsu [dot] edu.
