“…Type 3, Type 4 and Type 5 fibers have wide range of ZDWs with very low dispersion slope and hence support wide bandwidth optical signal processing. Moreover the dispersion variation in the HNLFs over S, C, L band is considerably low when compared to the previously reported results [26][27][28]. MFD is an important parameter connected with the optical field distribution in the fiber.…”

“…By increasing the width of the trench or dip next to the core (R 2 region), the dispersion slope of the fiber gets shifted to the longer wavelength side, while the increase in trench depth reduces the effective area of the fiber. In fact, many applications like four-wave mixing and supercontinuum generation encourage a dispersion profile with two ZDWs over the normal dispersion profile [4]. However, the splice loss and macro-bending loss of this profile, 1.1 dB and 6.548 × 10 −14 dB/km, respectively, still remain at a higher value.…”

“…Thus obtained highly nonlinear fiber (HNLF) can be a promising component for high bit rate all-optical signal processing applications like wavelength conversion, parametric amplification and supercontinuum generation. With the help of nonlinear phenomena such as self-phase modulation (SPM), cross-phase modulation (XPM) and fourwave mixing (FWM) along with femtosecond response, all the above-mentioned applications are achievable [2][3][4]. Although photonic crystal highly nonlinear fibers (PCF), chalcogenide and bismuth oxide fibers give very high nonlinear coefficients, they are not attractive because of their uncontrolled very high dispersion characteristic which in turn reduces the effective nonlinear interaction bandwidth of the fiber.…”

“…Initially, a HNLF with two zero-dispersion wavelengths (ZDWs) is more desirable than a fiber with a normal dispersion profile. Secondly, in order to integrate such fibers into the optical networks with SSMF, they should be capable of getting spliced [4]. Refractive index profile-based design of fiber plays an essential role in the design of silica-based fibers with fine properties such as dispersion, nonlinearity and cutoff wavelength [5,6].…”

In this paper, we demonstrate new dissimilar refractive index profiles for highly nonlinear ultra-flattened dispersion fibers with noteworthy effective area (A eff ) for future optical signal processing. The newly proposed fibers named from Type 1 to Type 5 have a flattened dispersion over S, C, L and U bands. Predominantly, few-mode HNL-UFF fiber of Type 3 yields dispersion-flattened characteristics over a range of 250 nm of optical communication spectrum with a mere 0.2 ps/nm km variation in dispersion and a dispersion slope of 0.0057 ps/nm 2 km due to the contribution of higher-order modes to the dispersion characteristics of the fiber. Moreover, it has a moderate nonlinear coefficient of 8.03 W −1 km −1 . By modifying the refractive index profile of Type 3 fiber, Type 4 and Type 5 fibers are obtained in order to ensure single-mode operation, while the zero flattened dispersion characteristics of the fiber are compromised. Among the newly proposed fibers, Type 4 fiber offers a very low ITU-T cutoff wavelength of 1.33 µm, whereas in the case of Type 5 fiber it is 1.38 µm. Moreover, Type 4 and Type 5 fibers have good nonlinear coefficients of 12.26 W −1 km −1 and 11.45 W −1 km −1 , respectively. By virtue of the proposed optimized index profile, an insensitive behavior toward bending is displayed by Type 3, Type 4 and Type 5 fibers. In addition, Type 4 fiber provides a better splice loss of 0.25 dB.Keywords Highly nonlinear ultra-flattened dispersion fiber (HNL-UFF) · Zero-dispersion wavelength (ZDW) · Refractive index profile · Effective area (A eff ) · Dispersion · Dispersion slope · Wavelength conversion (WC) B S.

An all-fiber Raman fiber oscillator operating at 2118 nm pumped by homemade thulium-doped fiber laser with continuous output power of 4.2 W has been demonstrated in this paper. By means of 26 m ultrahigh-numerical-aperture fibers, the average slope efficiency can be up to 23.6%. Because of the Raman spectrum broadening of the first Stokes light, the intensity of high order Raman Stokes has been suppressed. The mechanism of Raman spectrum broadening has been analyzed by group-velocity dispersion and Four-Wave Mixing frequency theories in detail. Two mode field adaptors have been used to reduce the intracavity loss and thermal deposition, which indicates that the proposed architecture is robust and has significant power scaling potential.
