Degenerate high-order hybrid bound states in the continuum beyond diffraction limit
Ji Tong Wang, Nicolae C. Panoiu
We demonstrate the existence of at- degenerate hybrid bound-states in the continuum (BICs) with high-order topological charges and quadratic band degeneracy in periodic photonic…
Hybrid Bound States in the Continuum beyond Diffraction Limit
Ji Tong Wang, Nicolae C. Panoiu
Bound states in the continuum (BICs) have greatly impacted our ability to manipulate light-matter interaction at the nanoscale. However, in periodic structures, BICs are typically…
Terahertz Emission from Spintronic Stack Nanodecorated with Drop-Cast Core-Shell Plasmonic Nanoparticles
Vittorio Cecconi, Akash Dominic Thomas, Ji Tong Wang +10
Spintronic emitters promise to revolutionise terahertz (THz) sources by converting ultrafast optical pulses into broadband THz radiation without phase-matching constraints. Because…
-matrix method for computation of second-harmonic generation upon optical wave scattering from clusters of arbitrary particles: Application to nonlinear optical interaction of bound states in the continuum
Ivan Sekulic, Ji Tong Wang, Jian Wei You +1
We derive the -matrix formalism tailored for numerical analysis of second-harmonic (SH) generation from arbitrarily shaped particles made of centrosymmetric optical ma…
Nonlinear optical metasurfaces empowered by bound-states in the continuum
Ji Tong Wang, Nicolae C. Panoiu
Optical bound-states in the continuum (BICs) have greatly enriched the field of nonlinear optics with novel ways to control and manipulate light-matter interaction at the nanoscale…
