Recent Advances in Photonic Bound States in the Continuum: From Fundamentals to Engineering and Implementation

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 ...

Enhancement and Speed‐Up of Carrier Dynamics in A Dielectric Nanocavity with Deep Sub‐Wavelength Confinement

Laser &Photonics Reviews, EarlyView.
This work presents the first experimental investigation of ultrafast dynamics in dielectric bowtie nanocavities, featuring deep‐subwavelength mode confinement. Measurements reveal enhanced two‐photon absorption, sub‐picosecond carrier relaxation, and strong pump–probe interactions, demonstrating clear advantages over conventional nanocavities for low ...

Mid‐Infrared Quantum Scanning Microscopy via Visible Light Beyond Spatial Correlations

Laser &Photonics Reviews, EarlyView.
This work introduces a raster‐scanning approach based on quantum imaging with undetected light (QIUL) that probes samples in the mid‐infrared (MIR) spectral range while performing detection in the visible domain. Unlike previous QIUL implementations, this technique operates independently of photon‐pair spatial correlations and relies solely on induced ...
