Stimulated Brillouin Scattering in Monomode Optical Fiber
TLDR
In this paper, the important dependence of the SBS gain and threshold on the spectrum and modulation parameters of the optical transmitter is discussed and possible techniques for suppressing SBS in optical communications systems are discussed.Abstract:
Stimulated Brillouin Scattering (SBS) has recently been observed in low-loss monomode fibers at power levels of only a few milliwatts. This article reviews the increasingly important influence which SBS will have on the design and operating range of future optical communications systems which employ low-loss fiber and narrowband laser transmitters. The important dependence of the SBS gain and threshold on the spectrum and modulation parameters of the optical transmitter is described. Possible techniques for suppressing SBS in optical communications systems are discussed.read more

TL;DR: In this paper, the phase mismatch in the four-wave mixing process is clarified experimentally in a single-mode fiber transmission line at 825 nm wavelength, and the generated power of approximately 20 pW is measured successfully for input signal powers below 1 mW by the technique utilizing a heterodyne receiver and lock-in detector.

TL;DR: Experiments show that radiation pressures, produced by subwavelength modal confinement, yield enhancement of Brillouin nonlinearity beyond those of material non linearity alone, which paves the way towards the hybridization of silicon photonics, microelectromechanical systems and CMOS signal-processing technologies on chip.

Experimental Observation of Picosecond Pulse Narrowing and Solitons in Optical Fibers
TL;DR: In this paper, the authors reported narrowing and splitting of 7-ps-duration pulses from a mode-locked color-center laser by a 700m-long, singlemode silica-glass fiber, at a wavelength (1.55 \ensuremath{mu}m) of loss and large but negative group-velocity dispersion.

Gaussian approximation of the fundamental modes of graded-index fibers
TL;DR: In this article, a direct numerical integration of the wave equation is used to establish the validity of approximating the fundamental mode of graded-index fibers by a Gaussian function, and the fundamental modes of fibers, whose index profile can be expressed as a power law, are indeed very nearly Gaussian in shape.
