Toward Reliable Metal Halide Perovskite FETs: From Electronic Structure and Device Physics to Stability and Performance Engineering

open access: yesAdvanced Electronic Materials, Volume 12, Issue 7, 6 April 2026.
Metal halide perovskite field‐effect transistors (PeFETs) offer great promise for flexible, low‐cost, and high‐performance due to their excellent charge carrier properties. However, challenges like ion migration, hysteresis, and instability limit their performance.

Laser Stabilized to a Fiber Interferometer With Close‐To‐Zero Temperature Sensitivity

open access: yesLaser &Photonics Reviews, Volume 20, Issue 8, 17 April 2026.
A laser stabilized to a hollow‐core fibre interferometer is presented. The interferometer is designed to have near‐zero temperature phase‐sensitivity. Laser stabilized to this interferometer put in a non‐vacuum environment achieves ±550 kHz frequency variation over 100 h and an Allan deviation of 2 × 10−14τ, which is comparable to miniature ULE ...

Chip-based microcavities coupled to NV centers in single crystal diamond

open access: yes, 2009
Optical coupling of nitrogen vacancy centers in single-crystal diamond to an on-chip microcavity is demonstrated. The microcavity is fabricated from a hybrid gallium phosphide and diamond material system, and supports whispering gallery mode resonances ...

Fast Simulation of Wide‐Angle Coherent Diffractive Imaging

open access: yesLaser &Photonics Reviews, Volume 20, Issue 7, 6 April 2026.
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.

Excitation of forced modes in the dielectric disk resonator-diffraction grating system [PDF]

open access: yesЖурнал нано- та електронної фізики, 2010
In this work the strip-like diffraction grating influence on the spectrum of “whispering gallery” modes of the disk dielectric resonator was studied experimentally. The conditions of single-mode excitation in a wide frequency range had been defined.

Effect of tapering diameters with microbottle resonator for formaldehyde (CH2O) liquid sensing

open access: yesSensing and Bio-Sensing Research, 2019
In this study, we demonstrate the effect of the microbottle resonator (MBR) based on whispering gallery modes (WGMs) with two different diameters of tapered microfibre and its experiment with the formaldehyde (CH2O) liquid sensor. The MBR with the bottle

On optical forces in spherical whispering gallery mode resonators

open access: yes, 2011
In this paper we discuss the force exerted by the field of an optical cavity on a polarizable dipole. We show that the modification of the cavity modes due to interaction with the dipole significantly alters the properties of the force.

Detecting light in whispering-gallery-mode resonators [PDF]

open access: yes, 2012
An optical device including a whispering gallery mode (WGM) optical resonator configured to support one or more whispering gallery modes; and a photodetector optically coupled to an exterior surface of the optical resonator to receive evanescent light ...
