Expression to predict the chromatic dispersion of a high-order mode in few-mode fibers

Second-order polarization-mode dispersion in photonic crystal fibers

Long distance transmission in few-mode fibers.

Using multimode fibers for long-haul transmission is proposed and demonstrated experimentally. In particular few-mode fibers (FMFs) are demonstrated as a good compromise since they are sufficiently resistant to mode coupling compared to standard multimode fibers but they still can have large core diameters compared to single-mode fibers. As a result these fibers can have significantly less nonl...

Rayleigh scattering in few-mode optical fibers

The extremely low loss of silica fibers has enabled the telecommunication revolution, but single-mode fiber-optic communication systems have been driven to their capacity limits. As a means to overcome this capacity crunch, space-division multiplexing (SDM) using few-mode fibers (FMF) has been proposed and demonstrated. In single-mode optical fibers, Rayleigh scattering serves as the dominant m...

Polarization-mode dispersion of large mode-area photonic crystal fibers

We report on an experimental study of the polarization properties of large mode-area photonic crystal fibers (PCFs). We find that such fibers may exhibit very low birefringence and polarization-mode dispersion (PMD) indicating a highly symmetrical hole structure over a long length. Moreover, the influence of temperature on the polarization-mode dispersion is investigated. The results show that ...

Polarization Mode Dispersion in Optical Fibers

In the previous chapter, we discussed devices based on deliberately introduced birefringence in an optical fiber, thus utilizing the polarization effects to our advantage. In Chapter 10, we discuss the detrimental aspect of birefringence in optical fibers—namely, polarization mode dispersion (PMD). The existence of birefringence in a fiber implies that the fiber supports two orthogonally polari...
