“…Extrusion techniques permit design freedom, but are typically restricted for soft glasses because those cause the material loss with severely high values. However, the proposed structure can be fabricated by currently developed technology for technological advancement in the fabrication of PCFs [51]. El et al [49] provided a sol-gel technique to fabricate the PCFs with all structures, and they provide the freedom to adjust air-hole size, shape, and spacing.…”

Abstract:In this paper, a hexagonal shape photonic crystal fiber (H-PCF) has been proposed as a gas sensor of which both micro-structured core and cladding are organized by circular air cavities. The reported H-PCF has a single layer circular core which is surrounded by a five-layer hexagonal cladding. The overall pretending process of the H-PCF is completed by using a full vectorial finite element method (FEM) with perfectly matched layer (PML) boundary condition. All geometrical parameters like diameters and pitches of both core and cladding regions have fluctuated with an optimized structure. After completing the numerical analysis, it is clearly visualized that the proposed H-PCF exhibits high sensitivity with low confinement loss. The investigated results reveal the relative sensitivity of 56.65% and confinement loss of 2.31×10 5 dB/m at the 1.33-m wavelength. Moreover, effective area, nonlinearity, and V-parameter of the suggested PCF are also briefly described.

“…For the first fabrication method, the proposed PCF can be fabricated by two step procedures. For a start, the double line defect core cane can be obtained by an extrusion method [36] and a mechanical drilling method [37]. Next, our proposed fiber design can be reliably fabricated by two-step stack-anddraw procedure due to all circular air holes and conventional lattice structure with core cane [38][39][40][41].…”

We propose a highly birefringent and dispersion compensating photonic crystal fiber based on a double line defect core. Using a finite element method (FEM) with a perfectly matched layer (PML), it is demonstrated that it is possible to obtain broadband large negative dispersion of about -400 to -427 ps/(nm.km) covering all optical communication bands (from O to U band) and to achieve the dispersion coefficient of -425 ps/(nm.km) at 1.55µm. In addition, the highest birefringence of the proposed PCF at 1.55 μm is 1.92 × 10 -2 and the value of birefringence from the wavelength of 1.26 to 1.8 μm (covering O to U bands) is about 1.8 × 10 -2 to 1.92 × 10. It is confirmed that from the simulation results, the confinement loss of the proposed PCF is always less than 10 -3 dB/km at 1.55 μm with seven fiber rings of air holes in the cladding.

“…The dual-core fiber preform was made by extrusion under a temperature around 600 o C. The extrusion method is a well-developed method for making non-silica glass (or so-called soft glass) HF [19] above the glass softening temperature, which is typically below 800 °C. It is very powerful in directly making microstructured preforms with glass features even as small as 7 µm [20].…”

We demonstrate the fabrication of a novel type of optical fibers with multiple parallel airsuspended cores by the sheet-stacking method. Using this technique we have constructed optical fibers with up to 10 parallel micron-size suspended cores. No extra scattering loss from the fabrication process was observed in a fabricated dual air-suspended core fiber. The sheetstacking method opens the way towards using a wide range of optical glasses for manufacturing multiple parallel suspended-core specialty optical fibers with novel optical functionalities such as dispersion tunability. Fusion splicing has also been successfully used to connect such a multiple core fiber with a conventional silica fiber.
