▪ Abstract The development of microstructured optical fibers has led to the realization of
many optical properties in fiber form that were not previously attainable. This chapter …

Optical fibres have for almost three decades been fabricated of solid glass. It was, therefore,
a radical change that took place, when researchers in the late 90's started to fabricate hair …

We assess different power limits of cladding-pumped fiber lasers. Despite recent advances
in pump sources, these are still primarily limited by available pump power. We find that it …

The amplification properties of different photonic crystal fibers have been studied by means
of a full vector finite-element modal formulation combined with a population and propagation …

An accurate model has been developed to study photonic crystal fiber Raman amplifiers.
The proposed approach calculates the Raman gain efficiency starting from the knowledge of …

Microstructured optical fibre is fabricated using extrusion. The main design of optical fibre
has a core suspended in an outer wall by a plurality of struts. A specially designed extruder …

We have developed a Nd: doped cladding pumped fiber amplifier, which operates at 938nm
with greater than 2W of output power. The core co-dopants were specifically chosen to …

Raman amplifiers based on photonic crystal fibers, whose cross section can be designed to
enhance the nonlinear properties, have been investigated in this work. The use of multiple …

We study both experimentally and theoretically power and spectral characteristics of two
types of Raman fiber lasers (RFLs) fully made with highly nonlinear photonic crystal fibers …
