Laser &Photonics Reviews, EarlyView.This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...

High quality two-dimensional photonic crystal slab cavities [PDF]
, 2001 We have fabricated and characterized donor-mode nanocavities formed by a single defect cavity defined within a two-dimensional photonic crystal slab. Quantum dots emitting in the 1.1-1.3 micron range were used as luminescence sources, and a design using ...

Laser &Photonics Reviews, EarlyView.Neural networks can accelerate modeling and inverse design of electromagnetic devices by several orders of magnitude, but usually require large amounts of data to train. This work demonstrates that integrating knowledge about quasinormal modes into the network architecture reduces the required amount of training data significantly, while simultaneously

Waveguiding power of photonic crystal slabs [PDF]
, 2007 We consider the waveguiding by thin patterned slabs embedded in a homogeneous medium. In the longwave limit, the wave spectra of slabs are found to be well described by a single frequency-independent parameter, which we call the "guiding power".

Laser &Photonics Reviews, EarlyView.Te@Se core–shell heterojunction quantum dots (QDs) are synthesized by a two‐step strategy via combining liquid‐phase exfoliation and epitaxial growth. As active materials in photoelectrochemical photodetectors, Te@Se QDs exhibit excellent photo‐response performance in low‐concentration electrolytes and deionized water.

Design and Fabrication of Silicon Photonic Crystal Optical Waveguides [PDF]
, 2000 We have designed and fabricated waveguides that incorporate two-dimensional (2-D) photonic crystal geometry for lateral confinement of light, and total internal reflection for vertical confinement.

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces
Laser &Photonics Reviews, EarlyView.Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Experimental demonstration of merging quasi-BICs in photonic crystal slabs
Materials & DesignMerging bound states in the continuum (BICs) and avoided crossing of resonances (ACR) are promising theoretical approaches to greatly enhance the quality (Q) factors of quasi-BICs in reciprocal space.

Long‐Range Polariton Canalization in a Graphene‐Nanoribbon–Covered MgTeMoO6 Metasurface
Nanophotonics, Volume 15, Issue 9, 13 May 2026.Simulated Re(Ez) field distributions at ω = 924 cm−1 for the graphene grating, MgTeMoO6 grating, the proposed hybrid structure, and the corresponding IFCs in (kx, ky) space are shown. Re(Ez) field maps in the x–y plane at ω = 924 cm−1 for Ef = 50, 70, 74, 76, 80, and 88 meV.

Line-Defect Waveguides in Hexagon-Hole type Photonic Crystal Slabs: Design and Fabrication using Focused Ion Beam Technology [PDF]
, 2003 Photonic-crystal slabs (PCS) patterned with a 2D triangular-lattice having hexagonal holes rotated with respect to their symmetry axis can provide a larger bandgap than similar slabs with circular holes.
