Hollow-bottle optical microresonators
Optics Express, 2011 Selective excitation of whispering-gallery and bottle modes in a robust hollow-bottle optical microresonator, fabricated from a silica microcapillary by a pressure-compensated, "soften-and-compress" method, is demonstrated. Characteristic resonance spectra of bottle modes were obtained by using a tapered fiber coupled at different locations along the ...

Photo‐Reconfigurable Supercoupling Induced Transparency in On‐Chip Topological Edge State Cavities
Advanced Materials, Volume 38, Issue 13, 3 March 2026.A novel supercoupling induced transparency (SIT) is demonstrated in a valley‐Hall photonic crystal. The valley vortices enable the supercoupling between a leaky and a guided topological edge state cavity even across a distance of 4.3 wavelengths, inducing a transparency window with negligible reflection.

An Alternative Approach to Spontaneous Photon Triplets Generation
Advanced Physics Research, Volume 5, Issue 3, March 2026.Day by day, communication and computing technologies are progressing at a lightning speed, which is particularly true of the quantum version of these technologies (QIST). Increasingly, these technologies are emerging from unusual and sometimes bewildering quantum optical effects, which are based on exotic quantum physical theories.

Dynamics of platicons due to third-order dispersion
, 2017 Dynamics of platicons caused by the third-order dispersion is studied. It is shown that under the influence of the third-order dispersion platicons obtain angular velocity depending both on dispersion and on detuning value. A method of tuning of platicon

Cathodoluminescence Enhancement Mechanisms in Silica Microspheres
Nanophotonics, Volume 15, Issue 6, 27 March 2026.Microspheres are prototypical optical resonators that affect cathodoluminescence (CL) in their surroundings. By resolving CL spectrally, spatially, and angularly, we disentangle the photon generation, absorption, and radiation mechanisms. We find two regimes: The first is dominated by CL from whispering gallery modes, which emanates exclusively from ...

Breather soliton dynamics in microresonators
Nature Communications, 2017 AbstractThe generation of temporal cavity solitons in microresonators results in coherent low-noise optical frequency combs that are critical for applications in spectroscopy, astronomy, navigation or telecommunications. Breather solitons also form an important part of many different classes of nonlinear wave systems, manifesting themselves as a ...
