Roadmap on structured waves
K. Y. Bliokh, E. Karimi, M. J. Padgett +47
Structured waves are ubiquitous for all areas of wave physics, both classical and quantum, where the wavefields are inhomogeneous and cannot be approximated by a single plane wave.…
Photonic Dirac Waveguides
Svetlana Kiriushechkina, Anton Vakulenko, Daria Smirnova +5
The Dirac equation is a paradigmatic model that describes a range of intriguing properties of relativistic spin-1/2 particles, from the existence of antiparticles to Klein tunnelin…
Roadmap on Topological Photonics
Hannah Price, Yidong Chong, Alexander Khanikaev +20
Topological photonics seeks to control the behaviour of the light through the design of protected topological modes in photonic structures. While this approach originated from stud…
All-optical nonreciprocity due to valley polarization in transition metal dichalcogenides
Yuma Kawaguchi, Sriram Guddala, Kai Chen +3
Nonreciprocity and nonreciprocal optical devices play a vital role in modern photonic technologies by enforcing one-way propagation of light. Most nonreciprocal devices today are m…
Photonic spin Hall effect mediated by bianisotropy
Dmitry V. Zhirihin, Sergey V. Li, Denis Y. Sokolov +3
Coupling of electric and magnetic responses of a scatterer known as bianisotropy enables rich physics and unique optical phenomena, including asymmetric absorption or reflection, o…
Valley selective optical control of excitons in 2D semiconductors using Chiral metasurface
S. Guddala, R. Bushati, M. Li +2
Recent advances in condensed matter physics have shown that the valley degree of freedom of electrons in 2D materials with hexagonal symmetry, such as graphene, h-BN, and TMDs, can…
