Integrated quantum photonics: challenges, opportunities, and emerging applications

Galan Moody, University of California Santa Barbara (United States)

Integrated photonics is revolutionizing how we generate, manipulate, and transmit quantum information. In this presentation, I’ll provide a background to the field, discuss how we design, fabricate, and test heterogeneous photonic devices, and highlight key results from my group and the community including emerging applications. I’ll particularly focus on two promising platforms for quantum such as AlGaAs and InGaP—two III-V semiconductor platforms that combine mature fabrication, a direct bandgap for electrical injection, high-Q resonators, heterogeneous integration with ultra-low-loss silicon nitride, and large optical nonlinearities for efficient quantum light generation and conversion. I’ll highlight some recent advances including: (1) multiplexing arrays of quantum sources for reconfigurable multi-user quantum networking, cryptography, and clock synchronization, (2) development and integration of tunable chip-scale lasers for turnkey and compact quantum modules, and (3) chip-scale squeezed microcombs for quantum-enhanced detectors and sensors. I’ll conclude with exciting future directions envisioned for engineering quantum photonic systems in the next 5-10 years.

Galan Moody is a Professor in the Electrical and Computer Engineering Department at the University of California Santa Barbara. Prior to this, he was a Research Scientist (2015-2019) at the National Institute of Standards and Technology (NIST) in Boulder, Colorado, and a National Research Council postdoctoral fellow at NIST (2013-2015). He received a PhD in Physics (2013) and a BSc in Engineering Physics (2008) from the University of Colorado Boulder. He is a recipient of a US Air Force Young Investigator Program award (2020), an NSF CAREER award (2021), an ACS Rising Star in Photonics Award (2024), and the UCSB College of Engineering outstanding faculty award (2024). He serves as a thrust co-lead and on the executive committee for UCSB’s NSF Quantum Foundry, chairs program committees for several conferences including FiOLS and CLEO, and he is on the editorial board for PRX Quantum and IOP’s Journal of Physics: Photonics.
