Near Infrared Supercontinuum Generation in Silica Based Photonic Crystal Fiber

“…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.…”

“…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.…”

“…Instead of using standard fibre, ytterbium doped photonic crystal fiber (Yb doped PCF) is used in [13], capable of generating SC spectrum with a 75 mW output power at a central wavelength of 1.064 µm from a 150 mW input signal wave. Reference [14] studies the performance of a CS 2 core photonic crystal fiber for SC application. It is demonstrated that the PCF is able to generate broadband SC spectrum in the IR region at central wavelength of 1.55 µm, with 100 W pump peak power.…”

Highly coherent supercontinuum generation in a polarization-maintaining CS2-core photonic crystal fiber

“…Moreover, the CS2 has reorientational nonlinearity response, which can accelerate the process of SF and improve the coherence of the SC [28,29]. Raj et al and Wang et al investigated the influences of the temperature and reorientational nonlinearity response on the SC generation [30,31]. Churin et al obtained mid-infrared SC of over 600 nm in an integrated CS2-core PCF [32].…”
