The Optoelectronics Technical Group invites you to join them for a webinar featuring Federico Cappaso focusing on metasurfaces, sub-wavelength scale artificially structured metal-dielectric surfaces, and their applications.

Metasurfaces enable the redesign of optical components into thin, planar, and multifunctional elements. This leads to a major reduction in thickness, footprint, and system complexity, ease of optical alignment and aberration control, as well as the introduction of new optical functions, thus circumventing the limitations of refractive and conventional diffractive optics. The planarity of flat optics facilitates the unification of semiconductor manufacturing and lens-making, where the planar technology to manufacture chips will be adapted to make CMOS-compatible metasurface-based optical components for high-volume markets and for specialty applications, ranging from metalenses to novel polarization optics and to multifunctional optical elements.

This webinar will cover the design, fabrication and measurements of metalenses, holograms, multifunctional metasurfaces and waveplates, with particular emphasis on polarization optics. Applications such as imaging, AR/VR (Augmented Reality/Virtual Reality), miniature spectrometers, polarimetry, and structured light will be discussed.

What You Will Learn: Assumes basic knowledge of the topic

What You Will Learn:
• Learn the physics of metasurfaces and principles to achieve wavefront control across the entire optical spectrum from the visible to the far-infrared
• Apply this knowledge to the design of meta-optical components for specific applications

Who Should Attend:
• Graduate students, postdoctoral researchers and faculty members
• Physicists and engineers working in industry

About the Presenter: Federico Capasso, Harvard University

Federico Capasso holds a Doctor of Physics degree from the University of Roma. He is the Robert Wallace Professor of Applied Physics at Harvard, which he joined in 2003 after 27 years at Bell Labs where his career advanced from postdoctoral fellow to Vice President for Physical Research. He has made wide ranging contributions to optics and photonics, nanoscience, designer materials leading to the invention of the quantum cascade laser; first measured the repulsive Casimir force. He pioneered metasurfaces and metaoptics, such as high performance metalenses. He is a co-founder of Metalenz Inc., focused on commercializing metaoptics for high-volume markets. He is Clarivate citation laureate for physics in 2023. His awards include the Balzan Prize, the King Faisal Prize, the AAAS Rumford Prize, the IEEE Edison Medal, the American Physical Society Arthur Schawlow Prize, the Optica Yves Medal. He is a member of NAS, NAE, NAI and a fellow of the American Academy of Arts & Sciences.
