All-optical programming of polarization singularities in a photonic-crystal laser
Abhishek Padhy, Zhiyi Yuan, Mohammed Hamdad +11
Singular optics has emerged as an important research area with diverse applications, yet controlling optical singularities in nanophotonic emitters remains largely constrained by t…
Chiral edge-state signatures of Berry monopole merging and splitting in a bilayer photonic crystal slab with synthetic momentum
Ngoc Duc Le, D. -H. -Minh Nguyen, Dung Xuan Nguyen +2
Berry monopoles are point degeneracies in parameter space where the Berry curvature emanates radially, analogous to magnetic monopoles. Here, we report the adiabatic merging and sp…
Shaping Bulk Fermi Arcs in the Momentum Space of Photonic Crystal Slabs
Luigi Frau, Simone Zanotti, Lydie Ferrier +2
Exceptional points (EPs) are special spectral degeneracies of non-Hermitian operators: at the EP, the complex eigenvalues coalesce, i.e., they become degenerate in both their real…
Breakdown of Bulk-Radiation Correspondence in Radiative Photonic Lattices
Xinyi Yuan, Loïc Malgrey, Helgi Sigurðsson +2
The topological characteristics of energy bands in crystalline systems are encapsulated in the Berry curvature of the bulk Bloch states. In photonic crystal slabs, far-field emissi…
Locally Hölder continuity of the solution map to a boundary control problem with finite mixed control-state constraints
Nguyen Hai Son, Tuan Anh Dao
The local stability of the solution map to a parametric boundary control problem governed by semilinear elliptic equations with finite mixed pointwise constraints is considered in…
Topological Lasing from Thouless Pumping in Bilayer Photonic Crystal
D. -H. -Minh Nguyen, Dung Xuan Nguyen, Hai-Chau Nguyen +5
Topological lasing leverages concepts from topological physics to achieve single-mode light amplification within topological bandgaps, offering robustness against fabrication imper…
