Nonlinear Optics in Specialty Optical Fibers

Dear Colleagues,

It is worth noting that 2021 is the 60th anniversary of the birth of nonlinear optics, and the upcoming 2022 will be the 50th anniversary of the birth of nonlinear fiber optics. As early as 1966, Kao (2009 Nobel Prize winner in physics) and Hockham proposed for the first time that the use of low-loss glass optical fibers could achieve high-efficiency transmission of information. After that, the rapid development of low-loss silica fiber fabrication technology not only set off a revolution in the field of optical fiber communications but also promoted the vigorous development of nonlinear fiber optics.

Especially since around 2000, specialty optical fibers represented by photonic crystal fibers (PCFs) have pushed the study of nonlinear effects in optical fibers to a new level. The unique structure of PCF with a periodic arrangement of air holes in its cladding not only results in adjustable fiber nonlinearity but also provides the opportunity of fine manipulation of fiber dispersion, making it widely used in multiple experiments of nonlinear optics. Of particular importance, the hollow-core PCFs based on anti-resonant reflection can guide light in gas over an extremely wide spectral range from ultraviolet to infrared, providing an ideal platform for studying light–gas interactions. Through adjusting the gas type and pressure inside the hollow core, waveguide dispersion and nonlinearity can be freely tuned over a broad range, leading to many fascinating nonlinear optics phenomena from sub-cycle pulse compression to high-efficiency dispersive wave emission.

In this Special Issue, we will present the most recent progressive developments in the field of nonlinear optics in specialty optical fibers, including supercontinuum generation, optomechanical effects, soliton dynamics, dispersive wave emission and so on. This Special Issue is collecting original research papers and reviews on “Nonlinear Optics in Specialty Optical Fibers”.
