Analysis of OH absorption bands in synthetic silica

Soliton Spectral Tunneling in Dispersion-Controlled Holey Fibers

“…Our model includes the exact calculated dispersion curves shown in Fig. 1 and the frequency dependence of the loss, α(ω), which we assume will be dominated by the intrinsic loss of the glass [8]. Fig.…”

Bandwidth comparison of photonic crystal fibers and conventional single-mode fibers

“…At a wavelength of around 820 nm the fiber no longer guides and a steep loss edge is observed. For the LMA-5 PCF (black curve), no cutoff is observed (the peaks at 1380 nm, 1245 nm, and 945 nm results from OH contamination [10]), and the fiber, thus, guides a single mode in the entire spectral range investigated. Although the attenuation level of the LMA-5 PCF is slightly higher than what can be realized, it is actually lower than or comparable to that of the conventional SMF for wavelengths lower than around 600 nm.…”

Revolver Hollow Core Optical Fibers

“…In the figure legend, the plotted experimental data are indexed by numbers in round brackets followed by references to literature in square brackets. More details are given in the text [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. [36] and in chalcogenide fibers at a wavelength of up to 6.5 µm [37,38].…”
