We report on the operation of regenerative sources based on self-phase modulation (SPM) and soliton self-frequency shift (SSFS). Such stochastic sources generate a wide continuum spreading over 450 nm.
We characterize the operation of self-pulsating sources made of two optical regenerators in cascade, namely a first regenerator of the type self-phase modulation spectral broadening and offset filtering, followed by a second regenerator of the type supercontinuum generation and offset filtering. The range of operation of this laser is explored as the wavelength and bandwidths of the band-pass filters...
A widely tunable wavelength converter based on the principle of soliton frequency shifting is proposed using non-uniform air-cladding As2Se3 microwires. The soliton dynamics are optimized analytically and numerically to reach mid-infrared wavelengths.
We propose an approach to design microwire waveguides that maximize wavelength-shift from 2.29 µm up to wavelengths in the mid infrared. The model is based on the optimization of soliton self-frequency shift and avoiding dispersive waves emission.
