“…Comparison is also made between the proposed HN-PCF, particularly at the centre wavelength values of 1.0 µm, 1.30 µm and 1.55 µm, and other fibers available in the literature [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] in terms of coherent power. This comparison is depicted in Table 3, showing fabricated fiber materials, center wavelength and coherent powers of the different optical fibers considered.…”

“…It should be highlighted that all the fibers considered are doped fibers with the exception of the fibers in [8,[24][25][26] and the proposed HN-PCF in this paper. It can be clearly seen from the table that the proposed HN-PCF achieves higher power values than other fibers [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Furthermore, the proposed HN-PCF is un-doped and hence, is relatively easier to fabricate than doped fiber.…”

“…Maximum average output power of 300 mW is successfully generated through the design in [16]. In [18], the authors demonstrate the generation of ultra-broadband SC spectrun with central wavelengths of 1.55 µm and 1.30 µm, using silica PCF with As 2 S 3 chalcogenide glass doped core. The SC generations use femtosecond pulse laser source with 3 kW peak power.…”

“…Various supercontinuum (SC) generated highly nonlinear photonic crystal fibers (HN-PCFs) have been reported in the literature for optical communications and medical applications [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], using different materials to produce broadband SC spectrum with varying performances.…”

“…Different designs of femtosecond (fs), picosecend and nanosecond pulse laser sources are proposed and consequently, investigated in references [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. In [10], the authors investigate the performance of femtosecond-laser pulses in neodymium-doped yttrium aluminium garnet (Nd:YAG) crystals and report that output power of around 1.3 W at around 1.0 µm center wavelength is achievable from an 2.25 W launched pump power.…”

This research explores a silica based highly nonlinear photonic crystal fiber of near infrared window; solid silica core photonic crystal fiber is suitable for propagating light towards the near-infrared wavelength region. Full vector finite difference method is used for numerical simulation, by solving the generalized nonlinear Schrödinger equation with the split-step Fourier method to show that the design exhibits high nonlinear coefficient, near zero ultra-flattened dispersion, low dispersion slope and very low confinement losses. It is demonstrated that it is possible to generate high power wide supercontinuum spectrum using 2.5 ps input pulses at 1.06 µm, 1.30 µm and 1.55 µm center wavelengths. It is observed that supercontinuum spectrum is broadened from 960 nm to 1890 nm by considering center wavelengths of 1.06 µm, 1.31 µm, and 1.55 µm into silica based index guiding highly nonlinear photonic crystal fiber. Furthermore, immensely short fiber length of 1 m at center wavelengths of 1.06 µm, 1.31 µm and 1.55 µm is possible using the proposed highly nonlinear photonic crystal fiber. The generated high power wide supercontinuum spectrum is applicable as a laser light source in near infrared band.
