Whispering gallery modes in open quantum billiards

, 2001
The poles of the S-matrix and the wave functions of open 2D quantum billiards with convex boundary of different shape are calculated by the method of complex scaling. Two leads are attached to the cavities.

Fast Simulation of Wide‐Angle Coherent Diffractive Imaging

Laser &Photonics Reviews, EarlyView.
The propagation multi‐slice Fourier transform method is introduced as an accurate and efficient approach for describing light scattering for arbitrarily shaped objects. Its exceptional suitability for simulating coherent diffractive imaging of nanoparticles in the XUV and soft X‐ray range is demonstrated.

Light and sound interplay in whispering gallery mode resonators

Journal of the European Optical Society-Rapid Publications
Whispering Gallery Mode Resonators (WGMRs) are robust and compact structures that confine resonant photons and phonons for extended time. This extraordinary confinement greatly enhances light and sound interactions and allows a plethora of fundamental ...

Chaos-assisted broadband momentum transformation in optical microresonators [PDF]

, 2017
The law of momentum conservation rules out many desired processes in optical microresonators. We report broadband momentum transformations of light in asymmetric whispering gallery microresonators.

Routes to spatiotemporal chaos in Kerr optical frequency combs

, 2014
We investigate the various routes to spatiotemporal chaos in Kerr optical frequency combs obtained through pumping an ultra-high quality whispering-gallery mode resonator with a continuous-wave laser.

Minor epic: Notes toward a different “Anthropoetry”

Anthropology 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

Method for predicting whispering gallery mode spectra of spherical microresonators

, 2015
A full three-dimensional Finite-Difference Time-Domain (FDTD)-based toolkit is developed to simulate the whispering gallery modes of a microsphere in the vicinity of a dipole source.

An Organic Semiconductor Lasing Crystal Featuring Triplet‐Triplet Annihilation

Aggregate, 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
