Multifunctional Metaoptics: From Science into Your Smartphones
Tue, Apr 15, 2025 1:00 PM - 2:00 PM EDT
Metasurfaces provide an almost unlimited toolbox to design the wavefront of light in search of new phenomena and applications. Using Matrix Fourier optics helped design the spatial distribution of Jones matrices to achieve polarization sensitive imaging, a new type of holography with control of polarization in the far-field and Mueller matrix imaging. Polarization metaoptics has led to an error-free biometric authentication system for smartphones. Federico Capasso, Ph.D. will present recent developments in large area metalenses for astrophysics as well as high efficiency broadband metalenses. Then will conclude with recent work on bilayer free-standing metasurfaces and the new functionalities that they enable. Sponsored by Pixelligent.

Laser-Based Particle Analysis: Enhancing Industrial and Biomedical Measurement Systems
Tue, Apr 29, 2025 1:00 PM - 2:00 PM EDT
In this in-depth webinar, Jeremy Lane, Managing Director of the ProPhotonix Laser Business Unit, will explore the critical role of semiconductor diode laser technology in the detection, characterization, and analysis of particulates and dispersion droplets across a wide range of industrial and biomedical applications. Laser light scattering is a widely adopted technique for particle analysis, often combined with complementary methods such as spectroscopy — many forms of which also utilize semiconductor diode lasers. Together, these technologies play a vital role in applications ranging from verifying the quality of the output in industrial manufacturing processes to detecting and quantifying airborne pollution and dust particles in environmental monitoring. In the biomedical field, laser-based systems are key to flow cytometry, where they are used to detect and characterize proteins on the surface of blood cells, measure cell size and shape, and support disease diagnostics. The webinar will also delve into how laser-based particle analysis is utilized to monitor dust concentrations in industrial environments, optimize milling processes, and aid in the development of new pharmaceuticals and food products. Don't miss this opportunity to learn how ProPhotonix's laser solutions can enhance your particle analysis applications across environmental, industrial, and biomedical sectors.
