“…The above values of cut-off between single-mode and multimode regions cannot be the same for elliptical core PCF. The exact value of the cut-off between single mode and multimode is an important parameter for applications like high power laser delivery in single-mode regime [29][30][31][32], to maximize the overlap amongst signal power, pump power and doped region at the core of an amplifier fiber [33][34]. The dispersion properties of this fiber; especially the tailoring of zero dispersion wavelength (ZDW) is extremely useful for numerous applications like broad-band supercontinuum generation (SCG) [35], ASE (Amplified Spontaneous Emission) suppressed amplifier [34], reduction of soliton fission in SCG [36] and different sources for Infrared (IR) applications [37].…”

In this work, we report detailed numerical analysis of the near-elliptic core index-guiding triangularlattice and square-lattice photonic crystal fiber (PCFs); where we numerically characterize the birefringence, single mode, cut-off behavior and group velocity dispersion and effective area properties. By varying geometry and examining the modal field profile we find that for the same relative values of d/, triangular-lattice PCFs show higher birefringence whereas the square-lattice PCFs show a wider range of single-mode operation. Square-lattice PCF was found to be endlessly single-mode for higher air-filling fraction (d/). Dispersion comparison between the two structures reveal that we need smaller lengths of triangular-lattice PCF for dispersion compensation whereas PCFs with square-lattice with nearer relative dispersion slope (RDS) can better compensate the broadband dispersion. Square-lattice PCFs show zero dispersion wavelength (ZDW) red-shifted, making it preferable for mid-IR supercontinuum generation (SCG) with highly non-linear chalcogenide material. Square-lattice PCFs show higher dispersion slope that leads to compression of the broadband, thus accumulating more power in the pulse. On the other hand, triangular-lattice PCF with flat dispersion profile can generate broader SCG. Square-lattice PCF with low Group Velocity Dispersion (GVD) at the anomalous dispersion corresponds to higher dispersion length (L D ) and higher degree of solitonic interaction. The effective area of square-lattice PCF is always greater than its triangular-lattice counterpart making it better suited for high power applications. We have also performed a comparison of the dispersion properties of between the symmetric-core and asymmetric-core triangular-lattice PCF. While we need smaller length of symmetric-core PCF for dispersion compensation, broadband dispersion compensation can be performed with asymmetric-core PCF. Mid-Infrared (IR) SCG can be better performed with asymmetric core PCF with compressed and high power pulse, while wider range of SCG can be performed with symmetric core PCF. Thus, this study will be extremely useful for designing/realizing fiber towards a custom application around these characteristics.

“…In the literature examples of PCFs doped with erbium 55 and/or ytterbium and with interesting properties for active 56 fibre and all-fibre amplifier devices can be found [9], and 57 different studies have been carried out on this technology in 58 order to improve the performance of rare earth doped fibre 59 amplifiers and lasers [10]. Following this idea we propose 60 a model for an erbium doped ARROW capable of guiding 61 both the wavelength of the peak of emission of the erbium 62 ion Er 3+ and the pump wavelength.…”

Erbium-doped antiresonant reflecting optical wave-1 guides (ARROWs) allow combining wavelength selective guiding 2 due to their attractive spectral versatility with an active opera-3 tion. In this letter, the analysis and design of a ring-type erbium-4 doped ARROW amplifier is presented. The influence of the 5 involved passive and active parameters (ring thickness and diam-6 eter, refractive index variation, pump and signal wavelengths, 7 Er 3+ -ion concentration, and input pump power) on the spectral 8 response of the structure and the optical power propagation losses 9 and on the amplifier performance is numerically analysed. The 10 opposite influence of the ring diameter on the optical power 11 confinement and on the pump power density causes the existence 12 of a diameter value that maximizes the amplifier net gain. For a 13 cladding refractive index of 1.4 and moderate index variations, 14 n = 0.2 − 0.4, the optimum ring diameter is in the range 15 of 20 μm. To compensate signal confinement losses (a few dB/cm), 16 high erbium concentrations (∼1 × 10 26 ion/m 3 ) are required. 17 Index Terms-ARROW, Er 3+ -doping, optical amplifier, opti-18 mized design.19
