Slow Light Propagation in a Thin Optical Fiber via Electromagnetically Induced Transparency [PDF]

, 2002
We propose a novel configuration that utilizes electromagnetically induced transparency (EIT) to tailor a fiber mode propagating inside a thin optical fiber and coherently control its dispersion properties to drastically reduce the group velocity of the ...

Effects of Noninvasive Respiratory Support on Ventilation Distribution During Spontaneous Breathing Sedation in Preschool/School‐Aged Children: An Electrical Impedance Tomography Study

Pediatric Anesthesia, Volume 35, Issue 7, Page 562-572, July 2025.
ABSTRACT Background Procedural sedation interferes with respiratory dynamics in pediatric patients. It reduces lung compliance, causing the closing volume to exceed the functional residual capacity, which can result in airway collapse, atelectasis, and periods of silent desaturation.

High contrast D$_{1}$ line electromagnetically induced transparency in nanometric-thin rubidium vapor cell

, 2011
Electromagnetically induced transparency (EIT) on atomic D$_{1}$ line of rubidium is studied using a nanometric-thin cell with atomic vapor column length in the range of L= 400 - 800 nm. It is shown that the reduction of the cell thickness by 4 orders as

EIT Observed Hypoxemia Caused by V/Q Mismatch During One‐Lung Ventilation With Indocyanine Green Inhalation: A Report of Two Cases

Respirology Case Reports, Volume 13, Issue 4, April 2025.
In this report, we present two cases monitored using Electrical Impedance Tomography (EIT), where individual differences in pulmonary blood flow redistribution contributed to hypoxemia. This phenomenon was further exacerbated in the lateral decubitus position with the ventilated lung in the upper position.
