Experimental Demonstration of Unified Kerr Nonlinear Effective Lengths for Gallium Phosphide‐On‐Insulator Photonic Devices

Advanced Photonics Research
Field enhancement (FE) plays a pivotal role in boosting the four‐wave mixing conversion efficiency (FWM CE)in photonic resonant cavities. While previous studies typically attributed this enhancement to intracavity power buildup, fewer have linked it to ...

Theoretical Study of Multicascade Raman Microlasers Based on TeO₂–WO₃–Bi₂O₃ Glass

Photonics, 2023
The development and investigation of miniature narrow-line coherent light sources based on microresonators with low-power-consumption whispering gallery modes (WGMs) is an actual trend in modern photonics. Raman WGM microlasers can operate at wavelengths

Optical Manipulation of Whispering Gallery Mode Microlasers for Controlled Cellular Delivery

Advanced Optical Materials, Volume 14, Issue 28, 24 July 2026.
Optically trapped whispering‑gallery microlasers are precisely positioned onto non‐phagocytic mammalian cells to report local refractive‑index changes in real time. Time‑dependent wavelength shifts reveal successive stages from membrane contact to internalization.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, Volume 5, Issue 7, July 2026.
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.

Experimental Demonstration of a Bottle Microresonator [PDF]

Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009
We demonstrate a very simple technique to fabricate robust microbottle resonators. Spheroidal WGMs and bottle modes were excited preferentially using a tapered fiber coupled at specific locations along the bottle, and characteristic resonance spectra obtained.

Germanium‐Based Mid‐Infrared Integrated Photonics

Laser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

A resonance system of an optoelectronic oscillator based on a transmission-type planar optical disk microcavity [PDF]

Компьютерная оптика, 2018
It is noted that the best technical characteristics of optoelectronic microwave self-oscillators (OESO) are reached in schemes employing high-Q optical microresonators (OMR) working in the traveling wave modes (TWM).

Optical‐to‐Microcomb Stability Transfer for Ultrastable Timing and Microwave/Millimeter‐Wave Generation

Laser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.

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 ...
