Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials

open access: yesLaser &Photonics Reviews, Volume 20, Issue 8, 17 April 2026.
This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

Ultra-thin optical power converters based on Gires–Tournois resonator configuration operating in high-order modes

open access: yesApplied Physics Express
In this study, we propose a strategy to construct high-performance ultra-thin optical power converters (OPCs) based on Gires–Tournois resonator configurations operating in high-order modes. Despite reducing the absorber thickness by 5.8 to 8.1 times, the

Laser Stabilized to a Fiber Interferometer With Close‐To‐Zero Temperature Sensitivity

open access: yesLaser &Photonics Reviews, Volume 20, Issue 8, 17 April 2026.
A laser stabilized to a hollow‐core fibre interferometer is presented. The interferometer is designed to have near‐zero temperature phase‐sensitivity. Laser stabilized to this interferometer put in a non‐vacuum environment achieves ±550 kHz frequency variation over 100 h and an Allan deviation of 2 × 10−14τ, which is comparable to miniature ULE ...

Mode‐Locked Pulse Generation in Plasmonic Lattices

open access: yesLaser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.
The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...

Digitally Tunable Dispersion Controller Using Low‐Loss Silicon Nitride Multimode Waveguide Gratings

open access: yesNanophotonics, Volume 15, Issue 8, 24 April 2026.
A digitally tunable dispersion controller (DTDC) using low‐loss silicon nitride multimode waveguide gratings is demonstrated. Utilizing cascaded chirped multimode waveguide gratings and Mach–Zehnder switches, the device achieves a tuning range of 0–49.72 ps/nm with 1.60 ps/nm steps over a 26‐nm bandwidth.

Reversible and Dynamic Tuning Mechanism for Fabry–Pérot Polaritonic Resonators

open access: yesNanophotonics, Volume 15, Issue 8, 24 April 2026.
We perform mid‐infrared nanoimaging on an air/α‐MoO3 nanocavity/VO2 heterojunction and realize dynamic, reversible tuning of phonon polariton resonances in a Fabry–Pérot nanocavity. This tunability arises from dielectric modulation via the thermally driven insulator‐metal transition of VO2, enabling nanoscale control of polariton behavior and offering ...

Phase Shift Compensation Enables Rainbow‐Free, Ultrawide Angular, and Pattern‐Free Nonreciprocal Thermal Emission

open access: yesNanophotonics, Volume 15, Issue 8, 24 April 2026.
A pattern‐free nonreciprocal emitter is demonstrated, exhibiting strong nonreciprocity (η > 0.6 or 0.8) across an unprecedented angular range (Δθ = 75° or 60°) at the target wavelength with monochromaticity of Δλ/λ₀ < 0.54%. The wavelength is tunable without compromising the rainbow‐free or ultrawide angular response, establishing a generalizable ...
