Supercontinuum generation in microstructured fibers and novel optical measurement techniques

Monitoring techniques for the manufacture of tapered optical fibers.

The use of a range of optical techniques to monitor the process of fabricating optical fiber tapers is investigated. Thermal imaging was used to optimize the alignment of the optical system; the transmission spectrum of the fiber was monitored to confirm that the tapers had the required optical properties and the strain induced in the fiber during tapering was monitored using in-line optical fi...

Birefringence in Optical Fibers: Applications

As discussed in the previous chapter, the so-called single-mode fibers in fact support two modes simultaneously, which are orthogonally polarized. In an ideal circular-core fiber, these two modes will propagate with the same phase velocity; however, practical fibers are not perfectly circularly symmetric. As a result, the two modes propagate with slightly different phase and group velocities. F...

Dispersion phenomena in optical fibers

Dispersion represents a broad class of phenomena related to the fact that the velocity of the electromagnetic wave depends on the wavelength. In telecommunication the term of dispersion is used to describe the processes which cause that the signal carried by the electromagnetic wave and propagating in an optical fiber is degradated as a result of the dispersion phenomena. This degradation occur...
