SUMMARY:Noise in Optical Measurements Workshop
DESCRIPTION:Workshop Leader: Prof. Emanuel Istrate\, Victoria College\, University of Toronto \n(Updated 2024/04/25)\nTime/Location\nWed\, May 1: 1:00-3:00pm\, GB244 (Theory)\nThu\, May 2: \, 1:30-3:00pm OR 3:30-5:00pm\, MP335 (Practical)\nTitle: Noise in Optical Measurements \n(Updated 2024/04/15)\nAbstract: This workshop will explore the physical processes underlying noise in measurements\, with a focus on optical measurements and the electronic circuits used to collect signals. An example calculation will illustrate how the magnitude of noise can be estimated and will be used to describe ways in which noise can be reduced. Finally\, a brief introduction will be provided to the use of lock-in amplifiers to extract signals from noise. The practical session (on the second day) will give a brief introduction to free-space optical alignment techniques and demonstration of using lock-in amplifiers to collect very weak signals. \nBio: Emanuel Istrate received his Ph.D. in Photonics from the University of Toronto in 2005. As the Academic Program Coordinator of the Institute for Optical Sciences at UofT\, he set up a number of courses and training programs in optics at all levels of the University. Part of his current teaching includes a course in the Vic One Arthur Schawlow program in the Physical Sciences\, which looks at communications and social interactions of scientists. He also teaches a course covering both the art and the science of holography\, as well as a course on creativity in the sciences. He has made contributions to lensless microscopy methods\, entrepreneurship training programs and to collaborative projects with industry. \nRegister here! \nDue to limited spots\, registering does not guarantee attendance. First come\, first served. Early year graduate students will be prioritized. Further information will be provided to those selected to attend. \nRegistration closes 11:59pm EST\, Thursday\, April 18\, 2024.

SUMMARY:Synchronization Dynamics of Nonlinear Photonic Oscillators
DESCRIPTION:Title: Synchronization Dynamics of Nonlinear Photonic Oscillators \nSpeaker: Prof. Alexander Gaeta\, David M. Rickey Professor of Applied Physics\, Columbia University \nDate and time: Tuesday\, May 14\, 2024\, 2-3 PM \nLocation: MP 134\, McLennan Physical Laboratories\, 255 Huron Street\, Toronto\, ON M5S 1A7 \nAbstract: \nSynchronization is a widespread phenomenon in the natural sciences\, shedding light on the behavior of coupled nonlinear dynamical systems. It also offers a powerful approach to robust frequency or temporal locking in diverse applications\, including communications\, superconductors\, and photonics. I will describe our work on the synchronization of soliton and non-solitonic photonic frequency combs in the fundamental\, harmonic\, and sub-harmonic regimes. I will also describe all-optical frequency division and the generation of ultralow-noise microwaves by synchronizing two distinct dynamical states of nonlinear photonic microresonators.  \nBio: \nGaeta received his doctorate in Optics from the University of Rochester. Gaeta joined Columbia University as the David M. Rickey Professor of Applied Physics and Materials Science in 2015. Prior to that\, Gaeta was the Samuel B. Eckert Professor of Engineering at Cornell University and was Chair of the School of Applied and Engineering Physics from 2011 – 2014. He has published more than 300 journal articles in quantum and nonlinear photonics. He served as the founding Editor-in-Chief of the journal Optica from 2014-2020. He co-founded Xscape Photonics\, Inc. and served as the CEO from 2021-2023.  He is a Fellow of the Optica\, APS\, and IEEE\, and a Thomson Reuters Highly Cited Researcher\, and received the 2019 Charles H. Townes Prize and the 2023 Stephen D. Fantone Distinguished Service Award.
