SUMMARY:Workshop / Seminar:Quantum Research Institute | Emerging Rare-Earth-Alloyed III-Nitrides for Quantum Photonics and Advanced Electronics
DESCRIPTION:Zoom: In the Meeting Invite\n\nIn-Person: Michigan Memorial Phoenix Project\, 2301 Bonisteel Blvd\, Ann Arbor\, MI 48109\, USA\, PML 2000\n\nAbstract:\nGroup III-nitride semiconductors have enabled a broad range of applications from solid-state\nlighting to high-power electronics. Alloying III-nitrides with rare-earth elements such as Sc\, Y\,\nand La offers new pathways to tailor their fundamental optical and electronic properties\, with\nsubstantial enhancements in piezoelectricity\, ferroelectricity\, and second-order optical\nnonlinearity (χ (2) ). These emerging materials offer a multifunctional platform for integrated\nquantum photonics and advanced electronics.\nIn this talk\, I will discuss the molecular beam epitaxy (MBE) growth and comprehensive\ncharacterization of several rare-earth-alloyed III-nitrides\, focusing on the effects of alloying on\nsecond-order optical nonlinearity and its role in enabling ferroelectric polarization switching. I\nwill then discuss the opportunities to develop new device concepts for both photonic and\nelectronic applications through heterostructure engineering. Specifically\, I will present an ultra-\nlow-loss hybrid ScAlN/SiNₓ integrated photonic platform for quantum photonics\, followed by\nelectronic device demonstrations in which ferroelectric ScAlN barriers are integrated into\nconventional high-electron-mobility transistors (HEMTs). These devices achieve record-low\nsheet resistance\, fast operation speed\, and exceptional thermal stability.\n\nBio:\nJiangnan Liu is a postdoctoral research fellow at the University of Michigan\, where he also\nearned his Ph.D. in Electrical and Computer Engineering. His research focuses on the molecular\nbeam epitaxy (MBE) growth and device integration of emerging ferroelectric III-nitride\nsemiconductors for the next-generation photonic and electronic applications.

SUMMARY:Workshop / Seminar:Quantum Research Institute | Scaling Quantum Technology with Integrated Photonics
DESCRIPTION:Zoom: In the Meeting Invite\n\nIn-Person: West Hall\, Room 411\n\nAbstract:\nQuantum technology including computing and sensing is gaining increasing\nattention and may become the next most important technology after A.I.\, at least that’s\nwhat their proponents would proclaim. Under the hood of these technologies\, however\,\nlurks a serious manufacturing problem that is partially documented in a recent Center\nfor New American Security report. This talk will outline quantum’s critical enabling\ntechnology problem in technical and economic terms. We will then focus on the future of\nintegrated photonics as one path to enabling the quantum technology future that many\nare excited to see come to fruition.\n\nBio:\nDr. John Burke is the Chief Product Officer at Beacon Photonics\, a technology start-up\ncompany developing integrated photonics and optical micro-systems for several dual-\nuse markets.\nPrior to this\, Dr. Burke was the Principal Director of Quantum Science in the U.S.\nDepartment of Defense\, for which he was awarded the Office of Secretary of Defense\nMetal for Exceptional Public Service. In the role\, he developed the Department’s\nstrategy\, oversaw the half a billion-dollar portfolio of programs\, and executed about a\nhundred million dollars a year.\nPreviously\, Dr. Burke was a Program Manager at DARPA after leading a research\nlaboratory for Air Force Research Lab\, developing optical atomic clocks\, quantum\ntechnology\, and photonic systems.\nDr. Burke received his Ph.D. from the University of Virginia in Atomic Physics.
