Universal coupled theory for metamaterial bound states in the continuum

New Journal of Physics, 2021
In this paper, we present a novel universal coupled theory for metamaterial bound states in the continuum (BIC) or quasi-bound states in the continuum (quasi-BIC) which provides ultra-high Q resonance for metamaterial devices.

Bound states in the continuum in photonic structures [PDF]

, 2022
Bound states in the continuum provide a remarkable example of how a simple problem solved about a century ago in quantum mechanics can drive the research on a whole spectrum of resonant phenomena in wave physics.

Engineering Perovskite Emissions via Optical Quasi-Bound-States-in-the-Continuum

, 2023
Metal halide perovskite quantum dots (PQDs) have emerged as promising materials due to their exceptional photoluminescence (PL) properties. A wide range of applications could benefit from adjustable luminescence properties, while preserving the physical ...

Increasing the Q‑Contrast in Large Photonic Crystal Slab Resonators Using Bound-States-in-Continuum

, 2023
Photonic-crystal surface-emitting lasers (PCSELs) have shown promise for large-area single-mode lasers. However, the difficulty in increasing PCSEL area while preserving single-mode operation has hindered the progress of achieving ultralarge-area PCSELs.

Anyonic bound states in the continuum

Communications Physics, 2023
Bound states in the continuum (BICs), which are spatially localized states with energies lying in the continuum of radiating modes, are discovered both in single- and few-body systems with suitably engineered spatial potentials and particle interactions.
