Advancing Quantum and Nano-Photonics with Machine Learning
Wed, Nov 1, 2023 1:00 PM - 2:00 PM EDT
The discovery of unconventional optical designs via machine learning promises to advance on-chip circuitry, imaging, sensing, energy, and quantum information technology. In this talk, Alexandra Boltasseva of Purdue University discusses photonic design approaches and emerging material platforms for showcasing machine learning-assisted topology optimization for optical metasurface designs with applications in thermophotovoltaics, reflective optics, quantum photonic circuitry, and lightsail technology. She demonstrates the effectiveness of autoencoders for compressing the vast design space of metasurfaces into a smaller search space.
Lock-in Amplifier or Boxcar Averager? Choosing the Right Measurement Tool for Periodic Signals
Thu, Nov 2, 2023 11:00 AM - 12:00 PM EDT
When it comes to analyzing periodic signals, selecting the appropriate measurement tool is crucial for achieving accurate and meaningful results. Gustavo Ciardi, Ph.D, an application scientist for optics and photonics at Zurich Instruments, delves into the theory behind two powerful techniques, lock-in amplification and boxcar averaging, to help individuals make informed decisions in their measurement endeavors. Additionally, he shares how to gain a deeper understanding of the techniques’ strengths, weaknesses, and the scientific contexts in which they excel. He aims to empower attendees with the knowledge needed to maximize signal-to-noise ratio, ensuring the highest precision in measurements. Presented by Zurich Instruments.
