Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

open access: yesFlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...

Whispering gallery resonator method for measurementspermittivity

open access: yesJournal of Telecommunications and Information Technology, 2002
The new method of measuring permittivity is described. The measurements are performed using whispering gallery mode open dielectric resonators. The accuracy is assured by applications of the mode matching method.

Will you teach me? From seriousness to sincerity with apprentice phenomenography

open access: yesThe Australian Journal of Anthropology, EarlyView.
Abstract By pushing for adequate modes of conceptualisation, ontological turn theorists have made significant headway in the attempt to take seriously ontological worlds that are typically considered irreconcilable to those of the Western intellectual project.

National Relics: Secular Sacrality, Museums, and Heritage‐Making in Nineteenth‐Century Chile

open access: yesMuseum Anthropology, Volume 49, Issue 2, Fall 2026.
ABSTRACT This article examines how objects and bodily remains are transformed and ritualized into national relics through collecting and exhibiting practices in museums. Focusing on nineteenth‐century Chile, it draws on archival sources, material culture theory, and the anthropology of religion to argue that objects associated with Chile's nation‐state

Observation of Whispering-Gallery Modes in a Diamond Microsphere

open access: yesIEEE Photonics Technology Letters, 2018
We demonstrate a Type Ib diamond (nitrogen impurity of >5 ppm) microsphere whispering-gallery mode resonator in the near-infrared wavelengths between 1426.10 nm and 1427.42 nm in the 90° elastic-light-scattering for both transverse magnetic (TM) and transverse electric (TE) polarizations.

Minor epic: Notes toward a different “Anthropoetry”

open access: yesAnthropology and Humanism, Volume 51, Issue 1, June 2026.
Abstract Anthropologists have often turned to poetry as a means of accessing emotional registers of which conventional academic prose is unable to avail. In doing so, they have tacitly conflated poetry with lyric poetry, today probably the most widely practiced poetic genre, associated in particular with the expression of inner feelings and subjectival

Whispering gallery modes for elastic waves in disk resonators

open access: yesAIP Advances, 2011
The resonant modes of elastic waves in disk resonators are computationally studied with the finite difference time domain method. Different materials examined for the disk such as platinum and silicon.

Harnessing Interfacial Field Localization in Hexagonal GaP Mie Resonators

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
Сharacterization of Mie modes in self‐assembled GaP nanowires grown by MBE in vertical and horizontal configurations. The hexagonal cross‐section suppresses higher‐order modes while preserving dominant low‐order modes with spectral shifts. Simulations and dark‐field spectroscopy confirm the diameter‐dependent tunability.

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells

open access: yesAdvanced Materials, Volume 38, Issue 25, 4 May 2026.
This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.

Locking a microsphere whispering-gallery mode to a laser

open access: yesOptics Express, 2001
We have locked a whispering-gallery resonance of a fused-silica microsphere to a frequency-scanning laser. The resonance frequency is modulated by axial compression of the microsphere, and phase-sensitive detection of the fiber-coupled optical throughput is used for locking.
