Over the past four years, there has been a surge of activity in the supercontinuum field since
the introduction of various types of microstructure fibers. The main reason for this great …

Solitons are wave packets that can propagate without changing shape by balancing
nonlinear effects with the effects of dispersion. In photonics, they have underpinned …

Recent progress on numerical modeling methods for photonic crystal fibers (PCFs) such as
the effective index approach, basis-function expansion approach, and numerical approach …

The first fiber Bragg gratings were accidentally written in a Ge-doped silica fiber using a high
power argon–ion laser [Hill 1978]. Following this first evidence of photosensitivity in optical …

In this paper, we summarize the research on photodarkening in optical fibers. The causes of
photodarkening in fiber, the influence of photodarkening on fiber laser, the experimental …

The dispersion properties of large-hole photonic crystal fibers (PCFs) are tailored by
changing the diameter of the air-holes belonging to the first three rings, in order to obtain …

We present experimental results on supercontinuum generation in a highly birefringent
microstructured fiber. We show that such a fiber offers clear advantages for continuum …

In this paper the guiding properties of photonic crystal fibers with a square lattice of air-holes
in a silica matrix have been studied for the first time. The dispersion curves of fibers with …

Yb-doped double-cladding photonic crystal fibers are one of the key enabling factors for the
development of high-power fiber lasers, due to their capability to provide a very large-mode …

The study reports on the design and performance of two air‐filled and two partial ethanol‐
filled photonic crystal fiber (PCF) structures with a tetra core for supercontinuum generation …
