Chirality-driven all-optical image differentiation
Stefanos Fr. Koufidis, Zeki Hayran, Francesco Monticone +2
Optical analog computing enables powerful functionalities, including spatial differentiation, image processing, and ultrafast linear operations. Yet, most existing approaches rely…
Coupling Light Waves to Gravitational Waves
Martin W. McCall, Stefanos Fr. Koufidis
We demonstrate analytically that gravitational waves, upon interacting with co-propagating electromagnetic radiation in a plasma, induce distinctive sidebands on the modulated ligh…
Light propagation in time-periodic bi-isotropic media
Stefanos Fr. Koufidis, Theodoros T. Koutserimpas, Francesco Monticone +1
Photonic structures and time-crystals, wherein time is incorporated as an additional degree of freedom for light manipulation, have necessitated the development of analytical and s…
Reverse Circular Bragg Phenomenon
Martin W. McCall, Stefanos Fr. Koufidis
The axial propagation of circularly polarized light in an optically active structurally chiral medium is exactly solved via full electromagnetic analysis. Some symmetries of the sy…
Broadband Bragg phenomenon in a uniform medium
Martin W. McCall, Stefanos Fr. Koufidis
A new mechanism of Bragg reflection is identified, one that, remarkably, occurs in a uniform medium and relies on resonant tuning of the medium's parameters. Due to uniformity, ref…
