“…The values of Lc at the pump wavelength of two fibers #F1 and #F2 are 74.554 dB/m and 11.106 dB/m. Although the Lc value obtained in our work is larger than previous publications [12,16], the fibers exhibit flat dispersion, a small dispersion value, and a high nonlinear coefficient suitable for the SC application. It should also be noted that it is difficult to simultaneously optimize the optical properties of PCFs.…”

“…The nonlinear coefficient of 83 W −1 .km −1 at 1.55 µm was obtained by designing GeO2-doped PCFs with a core refractive index higher than 3% [15]. GeO2-doped PCFs with octagonal structure exhibited nonlinearity as high as 4,500 W −1 .km −1 at 1,000 nm and confinement loss as low as 10 −9 dB/m at 1,800 nm [16]. The flatness and value of the dispersion can be controlled through adjustment of the GeO2 doping concentration, the authors [17] achieved a nonlinear coefficient of 0.0166 W −1 .m −1 and a small dispersion of −11.8 ps/(nm.km) at 1.55 μm, beneficial for wideband supercontinuum generation.…”

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. The dispersion of the square lattice fibers is a flatter and smaller value at the pump wavelength than the circular lattice fibers. Square lattice fibers with Ʌ = 0.9 µm, d1/Ʌ = 0.4 and Ʌ = 1.0 µm, d1/Ʌ = 0.45 are proposed for supercontinuum generation which has anomalous and all-normal dispersion, respectively. Their small dispersion values of 0.449 ps /nm.km and −1.096 ps/nm.km are suitable for broad spectrum supercontinuum generation. The small effective mode area and low attenuation of the two fibers of 3.221 µm2, 2.361 µm2 and 1.805×10−7 dB/m, 1.322×10−15 dB/m, respectively are favorable conditions for choosing a laser pump sources with low peak power. The proposed fibers can be new supercontinuum generation source replacing traditional glass core fibers.

“…Photonic gap guidance [8][9][10][11] allows the "air center" of hollow fibers to have a lower RI than the RI of the cladding material [12,13]. In practice, optical dispersion and birefringence of PCFs is often investigated [14][15][16][17]. Nowadays, PCFs are important since they can be implemented for many applications, such as supercontinuum light generation [18][19][20], light wavelength conversion [21,22], optical fluids [23], and different sensing area [24].…”

Solving the time-dependent power flow equation (PFE) provides a useful method to study the transmission bandwidth of step-index silica photonic crystal fibers (SI SPCFs). The transmission bandwidth of these kinds of fibers is determined for different air-hole structures (different numerical apertures (NAs)) and different distribution widths of the Gaussian launch beam. The results indicate that the lower the NA of SI SPCFs, the higher the bandwidth (for example, for a lower NA of SI SPCFs, a bandwidth that is eight times larger is obtained at a fiber length of 3500 m). The narrower launch beam at short fiber lengths results in a wider bandwidth. The longer the fiber (>300 m), the much less the effect of the launch beam width on the bandwidth. The bandwidth becomes independent of the width of the launch beam distribution at the fiber length at which a steady-state distribution (SSD) is reached. These results are useful for some potential applications, such as high capacity transmission optical fiber systems.

“…Hence, achieving high-accuracy RI sensors are of fundamental interest and play important roles in the biosensing fields. Nowadays, microstructured fibers with geometric versatility, and exceptional guiding properties, show unique advantage in constructing high-performance RI sensors [9][10][11][12] . Many photonic devices based on microstructured fibers usually adopt flame tapering or selective filling methods to make the fiber core close to the liquid materials, which could enhance the light-matter coupling ability and improve the sensing performance [13][14][15][16] .…”

Microstructured fibers with geometric versatility, and exceptional guiding properties, show unique advantage in constructing high-performance sensors. In this paper, a sensitivity-enhanced fiber-optic sensor based on an exposedcore single-hole microstructured fiber (SHMF) is proposed and experimentally demonstrated for the refractive index (RI) measurement of liquid samples. Experimental results show that the RI sensitivity of the exposed-core microstructured fiber is 375.77 nm/RIU in the low-range of 1.3409~1.3522. With the advantages of enhanced lightmatter interaction ability, tight light confinement and mechanical robustness, the proposed sensor based on exposedcore single-hole microstructured fiber offers great potential in biological and chemical sensing applications.
