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

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications
Laser &Photonics Reviews, Volume 20, Issue 20, 21 October 2026.Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Travelling, Staying, Working, Imagining: Space and the Practice of Internationalism, c1900–1950
History Compass, Volume 24, Issue 5, October 2026.ABSTRACT This article considers space as a key element in the practice of internationalism in the first half of the 20th century. Drawing on approaches in historical geography and cultural history, the article proposes four analytical categories through which internationalism might be explored in the period between 1900 and 1950.

Q-factor and waveguide-sphere separation effects in waveguide-coupled microsphere resonators
Quality-factors of waveguide coupled microsphere resonators of 30µm diameter are measured. A Teflon buffer layer is deposited on the waveguide to separate the microsphere from the waveguide and the effect of this separation on the measured quality-factor

Whispering gallery mode resonators with J-aggregates
Optics Express, 2011 We have studied the optical properties of a hybrid system consisting of cyanine dye J-aggregates attached to a spherical microcavity. A periodic structure of narrow peaks was observed in the photoluminescence spectrum of the J-aggregates, arising from the coupling between the emission of J-aggregates and the whispering gallery modes (WGMs) of the ...

Hybrid lasers based on CdSe/CdS core/shell colloidal quantum rods on silica microspheres
Single-mode lasing at ~628 nm above an absorbed pump power threshold of 67.5 µW, tunable within a 2.1 nm range (30% of the free-spectral-range) was obtained from colloidal CdSe/CdS core/shell nanorods on whispering-gallery-mode silica ...

Ultrahigh-Q Tunable Whispering-Gallery-Mode Microresonator
, 2009 Typical microresonators exhibit a large frequency spacing between resonances and a limited tunability. This impedes their use in a large class of applications which require a resonance of the microresonator to coincide with a predetermined frequency ...
