“…Of particular interest for wavelength conversion is the k = 1 Raman soliton because it is the shortest, the most powerful, and most importantly, it experiences the largest amount of SSFS. We however recently noticed numerically and experimentally that the k = 1 Raman soliton emerging from soliton fission often carries significantly more energy than predicted by the ISM, leading to ECE > ECEISM,1 [15].…”

“…This is particularly the case when an Nth order soliton or mother soliton (MS) experiences fission and splits into N fundamental solitons, from which solitons of femtosecond duration typically emerge [1,13]. Exploiting the soliton fission mechanism for SSFS based wavelength conversion has been reported by different groups [14][15][16]. For example, Gauthier et al reported the soliton fission of a MS into solitons experiencing SSFS for wavelength conversion up to 4.8 m in InF3 fiber [14].…”

“…The energy conversion efficiency (ECE) from the MS to each fundamental soliton is of practical interest for wavelength conversion applications. For instance, one may wish to optimize the energy transfer from the MS specifically towards the fundamental soliton that experiences the largest amount of SSFS [15,16].…”

We formulate the energy conversion efficiency from a high-order soliton to fundamental solitons by including the influence of interpulse Raman scattering in the fission process. The proposed analytical formula agrees closely with numerical results of the generalized nonlinear Schrödinger equation as well as to experimental results, while the resulting formulation significantly alters the energy conversion efficiency predicted by the Raman-independent inverse scattering method. We also calculate the energy conversion efficiency in materials of different Raman gain profiles such as silica, ZBLAN, and chalcogenide glasses ( A s 2 S 3 and A s 2 S e 3 ). It is predicted that ZBLAN glass leads to the largest energy conversion efficiency of all four materials. Energy conversion efficiency is a notion of utmost practical interest for the design of wavelength converters and supercontinuum generation systems based on the dynamics of a soliton self-frequency shift.

Emerging applications in the mid-infrared (MIR) stimulate the growth and development of novel optical light sources. Soliton self-frequency shift (SSFS) in soft glass fiber currently shows great potential as an efficient approach toward the generation of broadly tunable femtosecond pulses in the MIR. In this work, we demonstrate a highly efficient tunable soliton source based on SSFS in chalcogenide glass. We show a simple and fully fiberized system to generate these continuously tunable Raman solitons over a broad spectral range of 2.047–2.667 µm, which consumes no more than 87 pJ per pulse. The spectral measurements suggest that the generated pulses are as short as 62 fs with a maximum power conversion efficiency of 43%. This result is realized thanks to an 8 cm long A s 2 S 3 microstructure optical fiber tapered into a microwire. Thanks to their broad transparency, their high nonlinearity, and their adjustable chromatic dispersion, chalcogenide microwires are promising components for the development of compact and highly efficient MIR optical sources with low power consumption.
