Special Issue Information

Dear Colleagues,

This issue focuses on the very recent advances in nonlinear optics and its applications, which has been growing exponentially on various integrated platforms. Due to lower dimensions and strong light confinement, nonlinearity can be investigated using low laser powers and on micro-/nano-scales for a range of phenomena, including harmonic generation, frequency conversion, supercontinuum, and quantum bit manipulation, and over a wide optical range on fundamental research levels. The applications include optical clock, LiDAR, spectroscopy, imaging, detection, communication, etc. This Special Issue is aimed at including fascinating developments in all aspects of nonlinear optics and its applications including, but not limited to, the following areas:

  1. Nonlinear optics, like and -based nonlinearity;
  2. Integrated photonics on different material platforms;
  3. Novel photonics devices and applications;
  4. Ultrafast all-optical processing;
  5. Nonlinear waveguides and optical fiber;
  6. Nonlinear effects in nanostructures: plasmonics and metamaterials;
  7. Frequency combs;
  8. Nonlinear effects in microresonators;
  9. Terahertz/microwave photonics;
  10. Nonlinear imaging;
  11. Optical supercontinuum;
  12. Soliton and nonlinear localization effects;
  13. Nonlinear propagation and filamentation;
  14. Ultrafast dynamics and instabilities;
  15. Nonlinear quantum effects;
  16. Nonlinear optics for quantum information;
  17. Nonlinear topological, non-Hermitian systems;
  18. Attosecond and extreme nonlinear optics.

The influence of the interference between coherent processes in third-order nonlinear Raman scattering on the spectral shapes of Raman-scattered light waves is numerically modeled and discussed in the cases of commonly used coherent Raman spectroscopy techniques. The effects on the lineshapes depending on the laser intensity are analyzed for the coherent Raman spectroscopy performed via the excitation of molecular systems with focused laser pulses at high intensities. In this case, the interplay between the coherent processes in nonlinear Raman scattering, as well as laser power-induced resonance effects, may be significant and should be taken into account in the spectral lineshape analysis in coherent Raman spectroscopy and its related applications, since the coherent Raman spectra may be considerably modified.

This review focuses on phenomena such as temporal reflection, total internal reflection, and waveguiding from ultrashort solitons forming inside a nonlinear dispersive medium such as an optical fiber. The case of wider solitons, moving at a constant speed inside the fiber, is discussed first to introduce the basic concepts. In the case of short solitons, the phenomenon of intrapulse Raman scattering shifts their spectrum toward longer wavelengths and decelerates them as they propagate through an optical fiber. These features lead to several novel effects such as temporal focusing and waveguiding by a single variable-speed Raman soliton. Recent experimental results are also discussed in this context.
