Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects

Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Dynamic Evolution of a Storm‐Time “Super‐EPB” Event Over China on the Magnetically Disturbed Night of 01 December 2023

Space Weather, Volume 24, Issue 10, October 2026.
Abstract This paper investigates the dynamic evolution of a storm‐time “Super‐EPB” event over China on 1 December 2023 (Kp ≤ 7, SYM/H ≥ −130 nT) using multi‐instrument observations. Occurring near sunset as the IMF‐Bz abruptly turned southward, with auroral extension to midlatitudes, the “Super‐EPB” extended to 40°N with an apex height of ∼2,460 km ...

Two-dimensional ultrasound receive array using an angle-tuned Fabry-Perot polymer film sensor for transducer field characterization and transmission ultrasound imaging [PDF]

, 2005
A 2-D optical ultrasound receive array has been investigated. The transduction mechanism is based upon the detection of acoustically induced changes in the optical thickness of a thin polymer film acting as a Fabry-Perot sensing interferometer (FPI).

Equatorial F‐Region Responses to the Main Phase of the 10 May 2024 Geomagnetic Storm Over the South American Sector: Observations and Model Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study examines the equatorial ionospheric response over the South American sector during the onset of the extreme 2024 Mother's Day geomagnetic storm, which began at ∼17 UT on 10 May and reached the G5 level. Pronounced disturbances in ionospheric electrodynamics were observed under both daytime and nighttime conditions. Variations in the

First tristatic studies of meso-scale ion-neutral dynamics and energetics in the high-latitude upper atmosphere using collocated fpis and EISCAT radar [PDF]

, 2004
A unique experiment was undertaken during the nights of 27 and 28 February 2003. Tristatic Fabry-Perot Interferometer (FPI) measurements of the upper thermosphere were co-located with tristatic EISCAT radar measurements of the ionosphere.
