A Complex‐Frequency Framework for Kerker Unidirectionality in Photonic Resonators

Laser &Photonics Reviews, EarlyView.
ABSTRACT Electromagnetic scattering exhibits various anomalous behaviors, such as forward or backward scattering effects known as the Kerker conditions. These anomalies appear in non‐Hermitian photonic resonators and are mathematically described by operators with complex eigenfrequencies.

Revealing the Resonant Physics of Open Photonic Time Crystals

Laser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Side‐DBR Guided Exciton‐Polariton Lasing With Near‐Field Mode Imaging in an InGaN Thin‐Film Ridge Waveguide

Laser &Photonics Reviews, EarlyView.
Room‐temperature lower‐polariton‐like lasing is realized in an InGaN/GaN thin‐film ridge cavity with lateral distributed Bragg reflectors. Near‐field optical microscopy distinguishes the transverse side‐DBR‐confined mode from a longitudinal photon‐like mode, while simulations reproduce their spatial profiles.

Broadband Chromatic Dispersion of Thermo‐Refractive Coefficients and Its Impact in Silicon Nitride Nonlinear Photonics

Laser &Photonics Reviews, EarlyView.
Chromatic dispersion of material thermo‐refractive coefficients is characterized across an octave in integrated Si3N4${\rm Si}_3{\rm N}_4$/SiO2${\rm SiO}_2$ platforms. A 7% variation is observed from telecom to visible wavelengths, while incorporating this dispersion into multiphysics modeling captures frequency‐dependent resonance shifts and improves ...

Time‐Modulated Optomechanics Reveal Energy Flow and Inelastic Interactions Between Acoustic Phonons in Nanomembranes

Laser &Photonics Reviews, EarlyView.
Temporal interfaces are abrupt refractive index changes used in time‐varying optics, but also transitions to nonequilibrium states. This work explores the inelastic scattering of time‐varying light by nonthermal acoustic phonons in the vicinity of temporal interfaces.
