Germanium doped photonic crystal fibers with differences in the layers' air hole diameters in the cladding are presented to obtain flat dispersion, small effective mode area, and low attenuation property for supercontinuum generation applications. The flatness and small value of the dispersion depend on the lattice geometry when the fibers have the same germanium doping concentration.

This paper presents new results on dispersion in photonic crystal fibers (PCF) based on a circular lattice, with benzene infiltration into the hollow-core. We achieved near-zero, ultra-flat dispersion through the appropriate adjustment of air hole diameters and pitch of cladding.

In this paper, the nonlinear properties of photonic crystal fibers (PCF) with As2S3 substrate were analyzed numerically. With the suspended-core design, we achieve an anomalous dispersion regime with one or two zero-dispersion wavelengths, which is flat and has a small value at the investigated wavelength.

This study proposes a photonic crystal fiber made of fused silica glass, with the core infiltrated with chloroform as a new source of supercontinuum (SC) spectrum. We numerically study the guiding properties of the fiber structure in terms of characteristic dispersion and mode area of the fundamental mode.

As a result, octave spanning of the SC spectrum was achieved in the wavelength range of near-IR from 1.25 µm to 2.3 µm with 90 fs pulse and energy of 1.5 nJ at a pump wavelength of 1.55 µm. The proposed fibers are fully compatible with all-silica fiber systems, in particular, could be used for all-fiber SC sources and new low-cost all-fiber optical systems.

In this paper we present the development of a new direction in so-called optofluidics, namely the research of photonic crystal fibers (PCF) infiltrated with liquids. In particular we concentrate on the flagship application of PCF, the process of Supercontinuum Generation (SG), in which injected monochromatic pulse may be dramatically broadened (spectrally), which creates a coherent beam generation of high brightness comparable to that of monochromatic lasers.

This paper report simulation results of supercontinuum generation in the suspended-core optical fibers made of chalcogenide (As2S3) infiltrated with water at mid-infrared wavelength range. Applying water-hole instead of the air-hole in fibers allows improving the dispersion characteristics, hence, contributing to supercontinuum generations.

The characteristics of photonic crystal fibers (PCFs) with various air hole diameters infiltrated with alcoholic liquids such as ethanol, methanol, propanol and butanol are numerically investigated. Based on the numerical results, we have analyzed and compared in detail the characteristics of these fibers including effective refractive index, effective mode area, dispersion and confinement loss for two sets of parameters {d,Λ} = {1 µm,5 µm} and {1.42 µm, 3.26 µm}, with d the air hole diameter and Λ the lattice constant, respectively.

In this paper, we report a numerical calculation of the influence of structural parameters on the supercontinuum generation of photonic crystal fibers. A photonic crystal fiber based on the fused silica glass, eight rings of air holes ordered in a hexagonal lattice, is proposed. Guiding properties in terms of dispersion and confinement loss of the fundamental mode are also studied numerically. As a result, the broadband width of the supercontinuum spectrum will increase when the lattice pitch decreases or the diameter of air hole in the cladding increases.

In this paper, we report a numerical study of the supercoin (SC) generation in solid-core photonic crystal fibers infiltrated with water-ethanol mixtures. A photonic crystal fiber is constructed as borosilicate glass NC21, which consists of 7 rings of air holes infiltrated with water-ethanol mixtures. We also considered numerically the influence of concentration of the ethanol solution on the dispersion of the fundamental mode. SC generation was demonstrated for the fiber long 20 cm with a pump pulse of 200 fs, the coupled energy of 0.

the generation of ultrashort laser pulses. Beginning with mode-locking of glass lasers in the 1960s, the development of dye lasers brought the pulse width down from picoseconds to femtoseconds. The breakthrough in solid state laser pulse generation provided the current reliable table-top laser systems capable of average power of about 1 watt, and peak power density of easily watts per square centimeter, with pulse widths in the range of four to eight femtoseconds.
