In this webinar hosted by the OSA Fiber Modeling and Fabrication Technical Group, Dr. Jonathan Hu of Baylor University will describe the history, guiding mechanism, recent advances, applications, and future prospects for hollow-core negative curvature fibers. Hollow-core negative curvature fibers have drawn much attention in recent years. Due to their combined advantages of low loss, broad bandwidth, and a low power ratio in the glass, the hollow-core negative curvature fibers will be the best choice for a wide range of different applications.

This webinar will review one-dimensional slab waveguides, two-dimensional annular core fibers, and negative curvature tube lattice fibers to illustrate the guiding mechanism. In addition, the webinar will summarize recent advances in negative curvature fibers that improve the performance of the fibers, including negative curvature that increases confinement, gaps between tubes that increase confinement and bandwidth, additional tubes that decrease mode coupling, tube structures that suppress higher-order modes, nested tubes that increase guidance, and tube parameters that decrease bend loss. Finally, recent applications of negative curvature fibers will be presented, including mid-infrared fiber lasers, micromachining, and surgical procedures, and then future prospects for negative curvature fibers will be discussed.

What You Will Learn:

  • Basics of negative curvature fibers and guiding mechanism
  • Recent advances in negative curvature fibers
  • Applications using negative curvature fibers

Who Should Attend:

  • Undergraduate and graduate students
  • Educators and professors
  • Researchers in the optics and photonics industry
