Singlemode spatiotemporal soliton attractor

29 Gennaio 202113 Settembre 2021 tecnici

January 29th, 2021 Experimental and numerical studies of spatiotemporal femtosecond soliton propagation over up to 1 km spans of parabolic graded-index (GRIN) fibers reveal that initial multimode soliton pulses naturally and irreversibly evolve into a singlemode soliton. This is carried Read More …

Managing Self-Phase Modulation in Pseudolinear Optical Transmission Systems

13 Gennaio 20213 Marzo 2021 tecnici

January 13th, 2021 We propose a new semi-analytical model, describing the bandwidth evolution of pulses propagating in dispersion managed (DM) transmission systems using multimodal graded-index fibers (GRIN) with parabolic index. The model also applies to monomodal fiber DM systems, representing Read More …

Giving light a new twist: rainbow spiral emission

1 Ottobre 202013 Settembre 2021 tecnici

October 1st, 2020 We demonstrate a new practical approach for generating multicolour spiral-shaped beams. It makes use of a standard silica optical fibre, combined with a titled input laser beam. The resulting breaking of the fibre axial symmetry leads to Read More …

Upconversion luminescence in optical fibers

25 Settembre 20203 Marzo 2021 tecnici

September 25th, 2020 We experimentally demonstrate a previously unforeseen nonlinear effect in optical fibers: up-conversion luminescence generation excited by multiphoton absorption of femtosecond infrared pulses. We directly estimate the average number of photons involved in the up-conversion process, by varying Read More …

Distributed Kerr Lens Mode-Locking in Multimode Fiber Laser

20 Giugno 20203 Marzo 2021 tecnici

July 20th, 2020 We introduce a mechanism of stable spatiotemporal soliton formation in a multimode fiber laser. This is based on spatially graded dissipation, leading to distributed Kerr-lens mode locking. Our analysis involves solutions of a generalized dissipative Gross-Pitaevskii equation. Read More …
