SP1. "Machine learning for metamaterials and metasurfaces"

Organizer: Mohamed Bakr (McMaster University, Canada) and Willie Padilla (Duke University, USA)

Recent application of machine learning and deep learning has enabled accelerated design of metamaterial and metasurfaces, thus overcoming significant challenges with conventional numerical methods. For many metamaterial and metasurface systems, conventional optimization approaches are limited and not able to efficiently solve for a desired scattering response. The issue of finding the geometry of a metamaterial or metasurface that will give a desired spectral response – the inverse problem – is also is of keen interest and, as of yet, an unsolved problem. Research on machine learning, deep learning for accelerated metamaterial discovery and optimization, inverse neural networks, and interpretable machine learning, will be covered in the present session.

  1. Machine learning and deep learning for nanoscale structured materials;

SP23. "Topology in photonic crystals, metamaterials, and metasurfaces: physics and design"

Organizers: Yang Li and Benfeng Bai (Tsinghua University, China) 

Topology—the mathematics about conserved characteristics under continuous deformation—has been widely adopted by the photonic community to create interfaces supporting novel states of light and to design various photonic structures inversely. The former field, topological photonics, explores many exotic physical phenomena, such as robust unidirectional propagation of light, with potential applications. The latter inverse-design tool, topology optimization, enables many unprecedented photonic properties and functional devices, transforming the design methodology from intuition-based methods to performance-oriented approaches. This session will cover both the novel physics provided by topological photonics and metastructures designed by topology optimization.

Topics:

  1. Topological photonics;
  2. Photonic Dirac cone and its corresponding zero-index medium;
  3. ENZ, MNZ, and EMNZ medium: physics and applications;
  4. Inverse design in photonics: algorithms and applications;
  5. Photonic devices and systems for machine learning.

SP24. "Integrated lithium-niobate photonics: structures, devices, systems and applications"

Organizers: Xianfeng Chen (Shanghai Jiao Tong University, China) and Yang Li (Tsinghua University, China) 

Single crystal lithium-niobate film’s wide transparent window, high refractive index, and high second-order nonlinearity makes lithium-niobate on insulator (LNOI) an ideal material platform for integrated photonics. The fast development of fabrication techniques for LNOI enables ridge waveguides and structures with high index contrast and flexibility, enabling the integration of various structures, devices and systems onto a LNOI chip. This session will focus on the novel physics, methods, and applications that LNOI and ridge structures bring to the community of integrated lithium-niobate photonics.

Topics:

  1. LNOI waveguide, resonant cavity, and periodically poled lithium niobate (PPLN);
  2. LNOI-based electro-optic modulator, optical frequency comb;
  3. Applications of integrated LNOI devices in optical communications, nonlinear optics, quantum optics, microwave photonics, metrology, and optical computing.
