“…Each type of PCF has its unique strength; however, a hybrid of the two results in a PCF with fexible features [8]. Also, based on the fexible structure design, material use, and wide range of applications, PCF has recently received much more attention than conventional optical fbers [9][10]. Achieving the desired property in a PCF is often obtained by tailoring the geometrical properties of air holes in the cladding [11][12][13] and the optical properties of the dopant.…”

This paper presents a highly negative dispersion-compensating photonic crystal fiber (DC-PCF) with multiple zero dispersion wavelengths (ZDWs) within the telecommunication bands. The multiple ZDWs of the PCF may lead to high spectral densities than those of other PCFs with few ZDWs. The full-vectorial finite element method with a perfectly matched layer (PML) is used to investigate the optical properties of the PCFs. The numerical analysis shows that the proposed PCF, i.e., PCF (b), exhibits multiple ZDWS and also achieves a high negative chromatic dispersion of −15089.0 ps/nm·km at 1.55 μ m wavelength, with the multiple ZDWs occurring within the range from 0.8 to 2.0 μ m range. Other optical properties such as the confinement loss of 0.059 dB/km, the birefringence of 4.11 × 10 − 1 , the nonlinearity of 18.92 W − 1 k m − 1 , and a normalized frequency of 2.633 was also achieved at 1.55 μ m wavelength. These characteristics make the PCF suitable for high-speed, long-distance optical communication systems, optical sensing, soliton pulse transmission, and polarization-maintaining applications.

“…This is possible since the arrangement and the sizes of the air holes and the crystal lattice constant can be suitably adjusted to select the guidance of specific modes. MOFs are widely employed in high-power and energy transmission [5,6], fibre amplifiers [7], Brillouin scattering [8], supercontinuum generation [9], optical communications [10], stimulated Raman scattering [11], and optical sensors [12,13], among others. Specifically, SCFs are used to build gas and liquid sensing devices for chemical and biological applications [14], interferometer temperature sensors [15], and for nonlinear applications such as supercontinuum generation (SCG) [16,17].…”

Microstructured optical fibres (MOFs) are a new type of optical fibres that possess a wide range of optical properties and many advantages over common optical fibres. Those are provided by unique structures defined by a pattern of periodic or quasi-periodic arrangement of air holes that run through the fibre length. In recent years, MOFs have opened up new possibilities in the field of optics and photonics, enabling the development of advanced devices and novel optical systems for different applications. The key application areas of MOFs vary from telecommunications and high-power energy transmission to quantum optics and sensing. The stack-and-draw method is a standard manufacturing technique for MOFs, where a preform is first manually created and then drawn in a sophisticated furnace into a fibre with the required final dimensions and position of the air holes. During the manufacturing process, experimenters can control only a few parameters, and mathematical models and numerical simulations of the drawing process are highly requested. They not only allow to deepen the understanding of physical phenomena occurring during the drawing process, but they also accurately predict the final cross-section shape and size of the fibre. In this manuscript, we assume thermal equilibrium between the furnace and the fibre and propose a functional form of the fibre temperature distribution. We utilise it with asymptotic mass, momentum, and evolution equations for free surfaces already available in the literature to describe the process of fibre drawing. By doing so, the complex heat exchange problem between the fibre and the furnace need not be solved. The numerical results of the whole asymptotic model overall agree well with experimental data available in the literature, both for the case of annular capillaries and for the case of holey fibres.

“…HOTONIC crystal fibers (PCFs) intrigue many researchers due to the high flexibility of design and some unique optical properties, such as the endlessly single mode, high nonlinearity, high birefringence and ultraflatten dispersion [1][2][3][4] [5]. Therefore, PCFs can be used for many potential applications in telecommunications [6], sensing [7], non-linear optics [8] and other fiber devices. However, with the exponentially growing demand on communication capacity of signal transmission systems, to further increase the capacity of transmission media has become an urgent need [9].…”
