SUMMARY:CREOL Fall Colloquium: Galan Moody, University of California Santa Barbara

DESCRIPTION:Title: Advances in Heterogeneous Integrated Photonics for Scalable Quantum Technologies\n\nAbstract: Integrated photonics is revolutionizing how we generate, manipulate, and transmit quantum information. While the scalability and manufacturability of silicon photonics has been a driver of many quantum photonic technologies over the past two decades, future progress requires hybrid and heterogeneous integration strategies that can take advantage of different materials. In this presentation, I'll focus on AlGaAs and InGaP--two III-V semiconductor platforms that combine mature fabrication, a direct bandgap for electrical injection, low-loss operation, and large optical nonlinearities for efficient quantum light generation and conversion. After a brief introduction to the field, I'll discuss how we fabricate III-V photonic devices heterogeneously integrated with ultra-low-loss silicon nitride at wafer-scale, which we have utilized for high-rate entangled-photon pair generation and squeezing with performance that rivals bulk optics but with orders-of-magnitude smaller footprint and power requirements. I'll highlight some emerging applications, 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.\n\nAbout the Speaker: 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) 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 CU-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.\n\nVirtual Location URL: https://ucf.zoom.us/j/94633387918?from=addon
