Strong polarization mode coupling in microresonators

, 2014
We observe strong modal coupling between the TE00 and TM00 modes in Si3N4 ring resonators revealed by avoided crossings of the corresponding resonances. Such couplings result in significant shifts of the resonance frequencies over a wide range around the

Sharp Diamond Needles for Single‐Photon Emission

Advanced Photonics Research, Volume 7, Issue 2, February 2026.
We study the morphological evolution of single‐crystal diamond needles oxidized at 650–700 °C. Electron microscopy and photoluminescence reveal temperature‐ and time‐dependent sharpening, length reduction, and surface modifications affecting tip properties.

Dissipative Solitons in Microresonators

, 2022
In this Chapter we will illustrate the state-of-art in the generation of dissipative solitons in Kerr microresonator-based systems. After a brief introduction on the origin of this field of research, we will discuss the modeling of these microcavities using the generalized Lugiato-Lefever equation. Further, we will discuss the different techniques used
