Optical spin precession
Abanoub Mikhail, Maxim Mazanov, Ilya Deiry +3
Period-averaged electromagnetic spin angular momentum is a well-established quantity for monochromatic fields, governing phenomena such as light-matter interactions with chiral par…
Optical multistability in a compact microcavity enabled by near-exceptional coupling
Zhen Liu, Xuefan Yin, Andrey Bogdanov +5
Multistability -- the emergence of multiple stable states under identical conditions -- is a hallmark of nonlinear complexity and an enabling mechanism for multilevel optical memor…
MetaDiT: Enabling Fine-grained Constraints in High-degree-of Freedom Metasurface Design
Hao Li, Andrey Bogdanov
Metasurfaces are ultrathin, engineered materials composed of nanostructures that manipulate light in ways unattainable by natural materials. Recent advances have leveraged computat…
Sensing with Broken Symmetry: Revisiting Bound States in the Continuum
Brijesh Kumar, Elizaveta Tsiplakova, Samuel John +6
Metasurface with bound states in the continuum (BICs) offer exceptional potential for optical sensing due to their inherently high quality (Q) factors. However, the detection of sy…
Experimental observation of bulk Fermi arc in single dielectric resonator
N. Solodovchenko, F. Zhang, M. Bochkarev +4
The bulk Fermi arc is a fundamental non-Hermitian topological feature that connects two exceptional points (EPs), featuring the transition between Hermitian and non-Hermitian world…
