Second zero dispersion wavelength measurement through soliton self-frequency shift compensation in suspended core fibre

We present a detailed experimental parameter study on mid-IR supercontinuum generation in W-type index tellurite fibers, which reveals how the core diameter, pump wavelength, fiber length, and pump power dramatically influence the spectral broadening. As pump source, we use femtosecond mid-IR pulses from a post-amplified optical parametric oscillator tunable between 1.7 μm and 4.1 μm at 43 MHz repetition rate. We are able to generate red-shifted dispersive waves up to a wavelength of 5.1 μm by pumping a tellurite fiber in the anomalous dispersion regime between its two zero dispersion wavelengths. Distinctive soliton dynamics can be identified as the main broadening mechanism resulting in a maximum spectral width of over 2000 nm with output powers of up to 160 mW. We experimentally demonstrated that efficient spectral broadening with considerably improved power proportion in the important first atmospheric transmission window between 3 and 5 μm can be achieved in robust W-type tellurite fibers pumped at long wavelengths by ultra-fast lasers.

“…Figure 1(ab1) shows the dispersion curves of the two fibres considered. PCF A (black line) is similar to the commercially-available fibre Crystal Fiber NL-PM-750, with two ZDWs at 750 nm and 1230 nm [15]. The nonlinear coefficient at the 890 nm pump wavelength considered here is γ = 0.09 W −1 m −1 .…”

“…In the context of fiber SC generation, these extreme value statistics have been observed by studying the intensity characteristics of Raman solitons on the long wavelength edge of the SC generated in fibres with only one zero dispersion wavelength (ZDW) [6,7]. It is well known, however, that the use of PCF with two ZDWs significantly modifies the SC generation process, with the Raman self-frequency shift experienced by long wavelength solitons being arrested by the transfer of energy across the ZDW to a dispersive wave in the normal dispersion regime [13][14][15]. It would be expected that these modified dynamics would impact on the corresponding soliton statistical properties, and our objective here is to examine this question in detail.…”

Stochastic numerical simulations are used to study the statistical properties of supercontinuum spectra generated in photonic crystal fibre with two zero dispersion wavelengths. For picosecond pulse excitation, we examine how the statistical properties of solitons generated on the long wavelength edge of the supercontinuum ("optical rogue waves") are modified by energy transfer to dispersive waves across the second zero dispersion wavelength. The soliton statistics (characterized in terms of peak power, wavelength and pulse duration) are shown to be strongly modified by the mechanism of dispersive wave generation, with the detailed form of the probability distribution depending strongly on input pulse energy.

“…However, the frequency shift is stopped around 1250 nm when the pulse approaches the second zero dispersion wavelength of this fiber which has a concave dispersion profile. A dispersive wave is generated around 1350 nm 15 , which could be helpful to determine experimentally the position of the second ZDW 16 . Remark that for this fiber multiple solitons resulting from the initial pulse splitting are generated for initial energies as low as 90 pJ.…”

International audienceWe take advantage of the Raman soliton self-frequency shift experienced during the propagation in an anomalous dispersive photonic crystal fiber in order to continuously tune the central frequency of ultrashort pulses. We discuss the fiber properties to be favored to obtain high power spectral densities and we carry out an extensive experimental study of the properties of the frequency shifted pulses in terms of spectral, autocorrelation, and RF spectrum measurements
