Photonic Neuromorphic Computing enabled by a BIC Metasurface
Jingsong Fu, Ruiheng Jin, Zhaohui Xie +8
Photonic neuromorphic computing promises revolutionary advances in parallel and high-speed processing, yet a key challenge persists: co-integrating nonlinearity, dense connectivity…
Nonlinear chiral light generation from resonant metasurfaces
Fangxing Lai, Jun Yin, Ivan Toftul +6
Chiral nonlinear response has been explored for decades due to its extreme sensitivity to molecular and structural dissymmetry. Conventional approaches often require bulky systems…
Monoclinic nonlinear metasurfaces for resonant engineering of polarization states
Ivan Toftul, Dhruv Hariharan, Pavel Tonkaev +3
Polarization is a fundamental property of light that can be engineered and controlled efficiently with optical metasurfaces. Here, we employ chiral metasurfaces with monoclinic lat…
Intrinsically chiral exciton polaritons in an atomically-thin semiconductor
Matthias J. Wurdack, Ivan Iorsh, Sarka Vavreckova +15
Photonic bound states in the continuum (BICs) have emerged as a versatile tool for enhancing light-matter interactions by strongly confining light fields. Chiral BICs are photonic…
Chiral Dichroism in Resonant Metasurfaces with Monoclinic Lattices
Ivan Toftul, Pavel Tonkaev, Kirill Koshelev +4
We demonstrate that chiral response can be achieved in resonant metasurfaces with a monoclinic lattice symmetry (the so-called Bravais oblique lattices) where the mirror symmetry i…
Even-order optical harmonics generated from centrosymmetric-material metasurfaces
Pavel Tonkaev, Fangxing Lai, Sergey Kruk +4
Generation of even-order optical harmonics requires noncentrosymmetric structures being conventionally observed in crystals lacking the center of inversion. In centrosymmetric syst…
Chirality tuning and reversing with resonant phase-change metasurfaces
Xinbo Sha, Kang Du, Yixuan Zeng +8
Dynamic control of circular dichroism in photonic structures is critically important for compact spectrometers, stereoscopic displays, and information processing exploiting multipl…
Controllable distant interactions at bound state in the continuum
Haijun Tang, Can Huang, Yuhan Wang +4
Distant interactions at arbitrary locations and their dynamic control are fundamentally important for realizing large-scale photonic and quantum circuits. Conventional approaches s…
