Cavity QED with Diamond Nanocrystals and Silica Microspheres

, 2006
Normal mode splitting is observed in a cavity QED system, in which nitrogen vacancy centers in diamond nanocrystals are coupled to whispering gallery modes in a silica microsphere.

Modified permittivity observed in bulk Gallium Arsenide and Gallium Phosphide samples at 50 K using the Whispering Gallery mode method

, 2008
Whispering Gallery modes in bulk cylindrical Gallium Arsenide and Gallium Phosphide samples have been examined both in darkness and under white light at 50 K. In both samples we observed change in permittivity under light and dark conditions.

Fiber-coupled erbium microlasers on a chip [PDF]

, 2003
An erbium-doped, toroid-shaped microlaser fabricated on a silicon chip is described and characterized. Erbium-doped sol-gel films are applied to the surface of a silica toroidal microresonator to create the microcavity lasers.

Modulational instability and frequency combs in whispering-gallery-mode microresonators with backscattering [PDF]

, 2019
We introduce the first-principle model describing frequency comb generation in a whispering-gallery-mode microresonator with the backscattering-induced coupling between the counterpropagating waves.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Development of measuring system of whispering gallery mode resonances for evaluating a diameter of microsphere

Nihon Kikai Gakkai ronbunshu, 2019
A sphere is a frequently used shape as a reference of calibration for 3-dimensional measurement instruments because of its isotropic shape. It is demanded to measure the diameter of the reference sphere with high accuracy.

Inner structure of ZnO microspheres fabricated via laser ablation in superfluid helium

, 2017
ZnO microspheres fabricated via laser ablation in superfluid helium were found to have bubble-like voids. Even a microsphere demonstrating clear whispering gallery mode resonances in the luminescence had voids.
