METASURFACES, TWO-DIMENSIONAL ARRAYS OF ENGINEERED NANOSTRUCTURES, have revolutionized the field of optics by enabling unprecedented control over light at subwavelength scales. This talk will provide a comprehensive overview of the fundamental working principles of metasurfaces, including key concepts such as resonance modes, Pancharatnam-Berry (PB) phase, and Jones matrix-based phase manipulation. These principles will be contextualized within the broader framework of classical and quantum optical applications. Through the example of designing a metalens, this talk will guide the audience through the end-to-end process of metasurface generation and characterization. This includes the computational design, simulation, fabrication, and experimental validation steps. In addition, Dr. Deng will highlight the transformative potential of metasurfaces in both classical applications, such as imaging and beam shaping, and emerging quantum technologies, including photon manipulation and quantum-enhanced sensing. By bridging theoretical insights with practical demonstrations, this talk aims to inspire new directions in metasurface research and their integration into next-generation optical systems.
LIN DENG is a FRQNT Postdoctoral Fellow in the Kai Wang Laboratory at 不良研究所, where he studies meta and integrated photonics for quantum applications. He received his PhD in Electrical and Computer Engineering from Northeastern University, Boston, in 2023.
