“…The possibility of being able to control group velocity dispersion in PCFs, their small effective area, and elevated nonlinearity has allowed the observation of SC generation in a much wider range of source parameters than was possible with bulk media or conventional fibers [2]. Great progress has been made [3][4][5][6][7][8][9][10] during the last 15 years in the generation of SC employing PCFs.…”

In this paper, we investigate broadband supercontinuum generation in photonic crystal fibers using cosh-Gaussian optical pulses, which provide flatter spectrum than standard Gaussian pulses. This fact can be crucial for telecommunication systems applications. The intensive numerical study of three main telecommunication windows pointed out the most prominent window for spectral broadening. This finding offers the possibility of improving the characteristics of multi-wavelength sources and to enable wavelength density multiplexing systems.

“…Supercontinuum (SC) [5] generation in the visible spectral range has led to several breakthroughs in spectroscopy and imaging, most notably the development of the ultra-precise frequency comb used in optical metrology [6,7], but the broad spectrum has also been utilized in microscopy [8,9]. Recently, the supercontinuum technique was extended to the infrared spectral range beyond 2.6 μm by applying soft glass fibers such af ZBLAN [10,11].…”

Abstract:Combining the molecular specificity of the infrared spectral region with high resolution microscopy has been pursued by researchers for decades. Here we demonstrate infrared supercontinuum radiated from an optical fiber as a promising new light source for infrared microspectroscopy. The supercontinuum light source has a high brightness and spans the infrared region from 1400 nm to 4000 nm. This combination allows contact free high resolution hyper spectral infrared microscopy. The microscope is demonstrated by imaging an oil/water sample with 20 μm resolution. form spectroscopic imaging using an infrared focal-plane array detector," Anal. Chem. 67, 3377-3381 (1995). 18. L.
