“…The former is for slow axis and the latter for fast axis, referring to Ref. [9], which shows that the ZDW of the fast axis shift to a higher wavelength in HNMF with high birefringence and the ZDW splitting is proportional to the phase birefringence. The ZDWs along two axes are 1563nm and 1564.4nm, respectively.…”

“…Recently, it has been proposed that HNMF in telecom bandwidth shows intrinsic high birefringence, even splitting of zero dispersion wavelengths (ZDWs) along two axes, due to the asymmetries induced during fabrication. [9] However, the difficulty in dispersion measurement of the short HNMF sample near the ZDWs limits the study of its polarization dependent dispersion properties. The impacts of the polarization dependent dispersion on the nonlinear effects in HNMFs have not been explored comprehensively yet.…”

High nonlinear microstructure fibre (HNMF) is preferred in nonlinear fibre optics, especially in the applications of optical parametric effects, due to its high optical nonlinear coefficient. However, polarization dependent dispersion will impact the nonlinear optical parametric process in HNMFs. In this paper, modulation instability (MI) method is used to measure the polarization dependent dispersion of a piece of commercial HNMF, including the group velocity dispersion, the dispersion slope, the fourth-order dispersion and group birefringence. It also experimentally demonstrates the impact of the polarization dependent dispersion on the continuous wave supercontinuum (SC) generation. On one axis MI sidebands with symmetric frequency detunings are generated, while on the other axis with larger MI frequency detuning, SC is generated by soliton self-frequency shift.

“…These requirements can be somewhat relaxed by moving the birefringence closer to the flat slope maximum point, thereby reducing Δλ 0 at the same level of birefringence. However, this is only possible for fibers with λ 0 outside the telecom window, as it requires tighter mode confinement [43]. …”

Owing to the unique dispersion properties and high nonlinear coefficient, the small-core nonlinear photonic crystal fiber is among the most studied type in the class of microstructured fibers. We present a review of the basic aspects of nonlinear photonic crystal fibers with focus on dispersion design. The description of fiber design includes examples of fibers for use in both the telecom wavelength range and below. Moreover, we give an introduction to femtosecond supercontinuum generation and the effects of choice of pumping wavelength in relation to fiber dispersion. Finally, we present a range of application examples from the field of supercontinuum generation and telecommunication.

“…9 As long as PCFs fulfill their potentials, they could have important applications in spectroscopy, 10 metrology, 11 biomedicine, 12 imaging, 13 optical coherence tomography (OCT), 14 sensing, [15][16][17][18] and telecommunications. [19][20][21][22][23] On the other hand, although long-period gratings (LPGs) has emerged at the same time as PCFs, 24 the fabrications of PCF-based fiber components have attracted great attention in resent years. [25][26][27][28] LPGs typically have pitches in a range from 100 µm to 800 µm, based on the coupling between the fundamental core mode and the co-propagating cladding modes when the inter-modal beat period equals the grating pitch.…”

Although long-period gratings (LPGs) and photonic crystal fibers (PCFs) have emerged at the same time and been around for almost ten years, the fabrications of fiber components in PCFs have attracted great attention in resent years. Post processing of PCFs with a CO 2 laser is very powerful and versatile method for making miniature compact fiberbased devices including LPGs and phase-shifted LPGs. This article will review our research work on fabrication of those gratings in PCFs by use of focused beam from a CO 2 laser and point-by-point writing fashion. Either the mechanical stress relaxation technique or surface deformation method is employed in the design and fabrication of the gratings. The characterizations of the inscribed LPGs in PCFs at high temperature and high strain are also described. The potential applications of PCF-LPG devices for gas sensing have been discussed. Unlike the PCF-based gas sensor that detects the analytes by the interaction of light with gases through the absorption of the evanescent wave in the holes of fiber cladding, the PCF-LPG gas sensing works by the interrogating of the shifts of different resonance wavelength and strength of core-cladding mode coupling in the transmission spectrum. The advantages of the PCF-LPG sensing devices are: (1) high temperature insensitive and stability; (2) compactness when packaged; (3) practical use under hazardous conditions and in high temperature environment.
