Review of long period fiber gratings written by CO₂ laser

, 2010
This paper presents a systematic review of long period fiber gratings (LPFGs) written by the CO2 laser irradiation technique. First, various fabrication techniques based on CO2 laser irradiations are demonstrated to write LPFGs in different types of ...

Single Ion Coupled to an Optical Fiber Cavity [PDF]

Physical Review Letters, 2013
We present the realization of a combined trapped-ion and optical cavity system, in which a single Yb^+ ion is confined by a micron-scale ion trap inside a 230 mum-long optical fiber cavity. We characterize the spatial ion-cavity coupling and measure the ion-cavity coupling strength using a cavity-stimulated Lambda-transition.

Impact characteristics of needled/I-fiber coupling reinforced composite

Journal of Industrial Textiles, 2022
As a widely used thermal protection material for the aerospace vehicle, needled composites cannot avoid the impact load of the external environment during flight or reentry process, but the lack of continuous reinforcing fibers in the thickness direction

Coupling between guided modes of two parallel nanofibers

New Journal of Physics, 2020
We study the coupling between the fundamental guided modes of two identical parallel nanofibers analytically and numerically. We calculate the coefficients of directional coupling, butt coupling, and self coupling as functions of the fiber radius, the ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.
