From Single to Multi‐Material 3D Printing of Glass‐Ceramics for Micro‐Optics

Small Methods, EarlyView.
This article explores advancements in two‐photon lithography (TPL) for fabricating high‐refractive‐index micro‐optics. It examines single and multi‐material 3D architectures in glass and ceramics (GLACEs), highlighting photoresin customization, critical fabrication conditions, and cross‐scale structural and optical characterization.

Open whispering gallery mode resonators

Optics Letters
There are some issues with traditional whispering gallery mode (WGM) resonators such as poor light extraction and a dense mode spectrum. In this paper, we introduce a solution to these limitations by proposing open WGM (OWGM) resonators that effectively reduce the mode density and enable directional radiation through a connected waveguide at the ...

Effects of Nanocylinders on the Whispering Gallery Modes in a Microcylinder [PDF]

Sensors, 2016
Optical biosensors have been studied extensively for the detection and characterization of biological entities, such as viruses, bacteria, and biomolecules. A two-dimensional (2D) microcylinder resonator ( Q ∼ 2 × 10 5 ) was designed, and the effects of a nanocylinder on the whispering gallery modes (WGMs) were examined numerically.

Chip-scale high Q-factor glassblown microspherical shells for magnetic sensing

AIP Advances, 2018
A whispering gallery mode resonator based magnetometer using chip-scale glass microspherical shells is described. A neodynium micro-magnet is elastically coupled and integrated on top of the microspherical shell structure that enables transduction of the

Cylindrical Beam Propagation Modelling of Perturbed Whispering-Gallery Mode Microcavities [PDF]

arXiv, 2013
We simulate light propagation in perturbed whispering-gallery mode microcavities using a two-dimensional finite-difference beam prop- agation method in a cylindrical coordinate system. Optical properties of whispering-gallery microcavities perturbed by polystyrene nanobeads are investigated through this formulation.

Brillouin Lasing with a CaF_2 Whispering Gallery Mode Resonator [PDF]

, 2008
Stimulated Brillouin scattering with both pump and Stokes beams in resonance with whispering gallery modes of an ultra high Q CaF_2 resonator is demonstrated for the first time. The resonator is pumped with 1064 nm light and has a Brillouin lasing threshold of 3.5 microwatt.

Still here: age and generational time Encore là : âge et temps générationnel

Journal of the Royal Anthropological Institute, EarlyView.
The passage of generational time may be one of the most fundamental ways of experiencing ageing; we age in relation to others with whom our lives are intertwined – by becoming a grandmother or losing a father. Those of the oldest generation weaken and pass away, but in that process, they persist – for a while – with the younger generations.

Planar superconducting whispering gallery mode resonators [PDF]

Applied Physics Letters, 2013
We introduce a microwave circuit architecture for quantum signal processing combining design principles borrowed from high-Q 3D resonators in the quantum regime and from planar structures fabricated with standard lithography. The resulting “2.5D” whispering-gallery mode resonators store 98% of their energy in vacuum.
