Solid and hollow whispering gallery mode resonators for all optical switch [PDF]

open access: yesEPJ Web of Conferences
Whispering-gallery-modes resonators (WGMR) are effective switching devices when either coated or filled with non-linear material. We present examples of all-optical switching of hybrid WGM using polyfluorene, a methacrylate azobenzene and an acrylate ...

Exceptional Antimodes in Multi‐Drive Cavity Magnonics

open access: yesAdvanced Electronic Materials, EarlyView.
Driven‐dissipative cavity‐magnonics provides a flexible platform for engineering non‐Hermitian physics such as exceptional points. Here, using a four‐port, three‐mode system with controllable microwave interference, antimodes and coherent perfect extinction (CPE) are realized, enabling active tuning to antimode exceptional points.

Talbot interference of whispering gallery modes

open access: yesAPL Photonics
The Talbot self-imaging phenomenon is a fundamental interference effect that is natural to all waves with a periodic structure. We theoretically and experimentally study the Talbot effect for optical waves in the transverse angular domain using ...

Excitation of forced modes in the dielectric disk resonator-diffraction grating system [PDF]

open access: yesЖурнал нано- та електронної фізики, 2010
In this work the strip-like diffraction grating influence on the spectrum of “whispering gallery” modes of the disk dielectric resonator was studied experimentally. The conditions of single-mode excitation in a wide frequency range had been defined.

Trapping Electromagnetic Solitons in Cylinders

open access: yesMathematical Modelling and Analysis, 2014
Electromagnetic waves in vacuum or dielectrics can be confined in unbounded cylinders in such a way that they turn around the main axis. For particular choices of the cylinder's section, interesting stationary configurations may be assumed.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

open access: yesAdvanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Probing the strength of light–matter interaction in semiconductor microcavities by using resonant-mode shifts in temperature-dependent photoluminescence spectra

open access: yesAPL Materials, 2023
The Rabi-splitting energy represents the strength of light–matter interaction. This quantity is a good benchmark for evaluating the performance of light-modulation devices.
