Photonic Doping of Epsilon‐Near‐Zero Bragg Microcavities

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Photonic doping of an epsilon‐near‐zero (ENZ) Bragg microcavity at optical frequencies induces strong magnetic responses from dielectric inclusions, enabling intense field localization, Purcell enhancement, and tunable hybrid Bragg–Mie modes. The platform supports perfect magnetic conductor and epsilon‐and‐mu‐near‐zero regimes, offering opportunities ...

Nanophotonic Design of Germanium‐Silicon Single‐Photon Detectors for Integrated Quantum Photonic Circuits

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Nanophotonic Ge/Si single‐photon avalanche detectors (SPADs) employing photonic‐crystal‐enhanced optical confinement and a separate absorption–multiplication (SAM) architecture enable near‐unity internal quantum efficiency, low dark current, sub‐50 ps temporal response, and efficient telecom‐band single‐photon detection.

Magnetically Decoupled Janus Bound States in the Continuum for Chirality–Topology Control

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
This article demonstrates the Janus BICs, which are bi‐layer photonic crystal (PhCs) structures composed of C3v and magneto‐optical C6v symmetry slabs. It offers a unique platform for independent controlling chirality and topological charge, which successfully realizes the decoupling of topological charge and chirality.

Direct experimental visualization of waves and band structure in 2D photonic crystal slabs

New Journal of Physics, 2014
We demonstrate for the first time the ability to perform time resolved imaging of terahertz (THz) waves propagating within a photonic crystal (PhC) slab.

Brillouin Zone Folding‐Driven Topological Band Flips Based on BICs via Twisted Photonic Crystals

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
Brillouin zone folding (BZF)‐driven topological band flips are demonstrated via twisted photonic crystals (PhCs) incorporating bound states in the continuum (BICs). Twist perturbation generates three new bands, each linked to either a BIC or a guided‐mode resonance (GMR).

Multi‐Mode Deep Strong Coupling in a Multi Quantum Well Fabry–Perot Cavity

Advanced Optical Materials, Volume 14, Issue 21, 5 June 2026.
Multi‐mode deep‐strong coupling is demonstrated in a 166‐well heterostructure that acts as a Fabry–Perot cavity. Even cavity modes couple strongly to the cyclotron resonance, producing large vacuum Rabi splittings and a rich polaritonic spectrum captured by a full Hopfield model.

High temperature, experimental thermal memory based on optical resonances in photonic crystal slabs

APL Photonics, 2019
We present an experimental thermal memory with direct optical control and readout. Information is stored in the internal temperature of the device, while laser illumination is used to read, write, and erase stored bits.
