1. Introduction. As a localized stably nonlinear waveform, an optical soliton is generated by a balance between fiber dispersion and nonlinearity effect [1].Since the first theoretical study of optical solitons in 1973 [2], multifarious optical solitons have been theoretically and experimentally investigated over the past decades.Meanwhile, as

Optical fiber sensors can be used advantageously for monitoring dams and levees and to detect and localize damage in them.

A multimode optical fiber supports excitation and propagation of a pure single optical mode, i.e., the field pattern that satisfies the boundary conditions and does not change along the fiber. When two counterpropagating pure optical modes are excited, they could interact through the stimulated Brillouin scattering (SBS) process. Here, we present
The theory of Rayleigh scattering results from the interaction of light from non-propagating density fluctuations is discussed within [41, 42].Optical frequency domain reflectometry (OFDR) is one of the schemes employed for high spatial resolution sensing [43].As discussed within [44, 45] Coherent-OFDR is one of the most appropriate means
A double cavity fiber FP sensor is a unique example of the intrinsic FP sensors with two cavities created by a holey optical fiber fusion spliced between a single mode and a multi-mode optical fiber.

In 2007, Zhu et al. reported light storage based on SBS. 98 In this approach, the optical data pulses are not slowed down by the dispersive phase slope of the SBS resonance but are rather transferred to the acoustic wave via the resonant interaction between the optical data pulse and a second optical pump offset by the Brillouin
