Minor epic: Notes toward a different “Anthropoetry”
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
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

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
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
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 ...

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.

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.

Optothermal dynamics in whispering-gallery microresonators
Optical microresonators: Investigating light’s tiny whispers Optical whispering-gallery mode microresonators can trap light in a highly confined volume, similar to the behavior of sound waves in the famous whispering gallery of St Paul’s Cathedral ...

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
