Fiber Bragg gratings in optical microfibers

Bulk regeneration of optical fiber Bragg gratings.

The reliability and reproducibility of regenerated gratings for mass production is assessed through simultaneous bulk regeneration of 10 gratings. The gratings are characterized and variations are compared after each stage of fabrication, including seed (room-temperature UV fabrication), regeneration (annealing at 850°C), and postannealing (annealing at 1100°C). In terms of Bragg wavelength (λ(...

Solitons in Bragg Gratings with Saturable Nonlinearity

Coupled-mode equations for two waves coupled by the Bragg reflection in the presence of saturable nonlinearity are introduced. Stable solitons and their bound states fill a part of the bandgap, their collisions being quasi-elastic.

Na<SUP>+</SUP>-K<SUP>+</SUP>ATPase in Human Brain Tumors

Na+-K+-stimulated adenosine triphosphat s (Na+-K+ATPase) activities were measured in 12 human brain tumors and surrounding tissue (white matter and cortex) by the colorimetric deter mination of hydrolyzed inorganic phosphorus (Pi) from adenosine triphosphate (ATP). In glioma cases, the brain microvessels, filial component, and neurons were isolated fr...
