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

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

open access: yesAIP 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

High Q-factor Sapphire Whispering Gallery Mode Microwave Resonator at Single Photon Energies and milli-Kelvin Temperatures

open access: yes, 2011
The microwave properties of a crystalline sapphire dielectric whispering gallery mode resonator have been measured at very low excitation strength (E/hf=1) and low temperatures (T = 30 mK). The measurements were sensitive enough to observe saturation due

An Organic Semiconductor Lasing Crystal Featuring Triplet‐Triplet Annihilation

open access: yesAggregate, Volume 7, Issue 2, February 2026.
An organic semiconductor crystal emitter of BH001 is reported to exhibit stimulated emission with the aid of triplet‐triplet annihilation (TTA). The crystal achieves low‐threshold blue laser emission (Pth = 15.4 µJ/cm2) under femtosecond pulsed laser excitation. Notably, stimulated emission persists even when pumped by nanosecond lasers, indicating its

Direct Writing of Photonic Structures by Two-Photon Polymerization

open access: yesMATEC Web of Conferences, 2013
Single-mode dielectric-loaded surface plasmon-polariton nanowaveguides with strong mode confinement at excitation wavelength of 830 nm and high-Q polymer whispering gallery mode microcavities with surface roughness less than 12 nm have been directly ...

A unified approach to mode splitting and scattering loss in high-Q whispering-gallery-mode microresonators

open access: yes, 2012
Current theoretical treatment of mode splitting and scattering loss resulting from sub-wavelength scatterers attached to the surface of high-quality-factor whispering-gallery-mode microresonators is not satisfactory.

Narrow Linewidth Spontaneous and Lasing Emissions from Open‐Access Microcavity‐Embedded Perovskite Quantum Dots

open access: yesAdvanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.

Toward Rapid Low‐Cost Fabrication of Single‐Nanowire Photodetectors via the Utilization of Dielectrophoresis

open access: yesAdvanced Photonics Research, Volume 7, Issue 1, January 2026.
A scalable, low‐cost approach for assembling single germanium nanowires (NWs) into photodetectors is demonstrated using a modified dielectrophoresis method with a voltage‐divider circuit. This self‐limiting assembly technique achieves ultrahigh responsivity (>6 × 105 A W−1) at 700 and 1550 nm without requiring nanoscale electrodes, offering a versatile
