Increasing the blue-shift of a supercontinuum by modifying the fiber glass composition

Influence of pump power and modulation instability gain spectrum on seeded supercontinuum and rogue wave generation

“…Many of these applications require spectra with high power density in the visible part of the spectrum, which can be achieved in nonlinear fibers with a group-velocity (GV) profile that allows GV matching between long wavelength solitons and dispersive waves at visible wavelengths [2]. The concept of GV matching has been used to show how the spectra can be extended into the deepblue by optimizing the fiber structure [3], by tapering the fiber [4][5][6], or by doping the fiber [7]. Other ways of pushing the spectrum toward the blue include seeding with the second harmonic [8], using concatenated fibers [9], or back-seeding part of the SC [10][11][12].…”

Nonlinear photonic crystal fiber with a structured multi-component glass core for four-wave mixing and supercontinuum generation

“…Fiber fabrication with exotic glasses is complex especially when different types of glasses are mixed. Recently, a numerical study was reported where PCFs with different glass compositions were compared in order to modify the dispersion properties of the microstructured fibers and to increase the generation of blue wavelengths [9][10][11]. Additionally, it has already been demonstrated that the presence of a central air hole in the PCF core enables stabilization of the soliton selffrequency shift (SSFS) and generation of a broadband four-wave mixing process (FWM) [12].…”

Highly sensitive and simple method for refractive index sensing of liquids in microstructured optical fibers using four-wave mixing

“…4 in Ref. [32]). We find that the higher loss experienced by the Stokes wave in the near-infrared does not significantly reduce the growth of the antiStokes wave in the visible, in accordance with previous findings [33].…”
