Low-noise octave-spanning mid-infrared supercontinuum generation in a multimode chalcogenide fiber
Zahra Eslami, Piotr Ryczkowski, Lauri Salmela +1
We demonstrate the generation of a low-noise, octave-spanning mid-infrared supercontinuum from 1700 to 4800 nm by injecting femtosecond pulses into the normal dispersion regime of…
Computational spectral-domain single-pixel imaging
Piotr Ryczkowski, Caroline Amiot, John M. Dudley +1
We demonstrate single-pixel imaging in the spectral domain by encoding Fourier probe patterns onto the spectrum of a superluminescent laser diode using a programmable optical filte…
Interferometric Autocorrelation Measurements of Supercontinuum based on Two-Photon Absorption
Shanti Toenger, Roosa Mäkitalo, Jani Ahvenjärvi +4
We report on interferometric autocorrelation measurements of broadband supercontinuum light in the anomalous dispersion regime using two-photon absorption in a GaP photodetector. T…
Ghost optical coherence tomography
Caroline Amiot, Piotr Ryczkowski, Ari T. Friberg +2
We demonstrate experimentally ghost optical coherence tomography using a broadband incoherent supercontinuum light source with shot-to-shot random spectral fluctuations. The techni…
Broadband continuous spectral ghost imaging for high resolution spectroscopy
Caroline Amiot, Piotr Ryczkowski, Ari. T. Friberg +2
Ghost imaging is an unconventional imaging technique that generates high resolution images by correlating the intensity of two light beams, neither of which independently contains…
Real-time measurements of dissipative solitons in a mode-locked fiber laser
P. Ryczkowski, M. Närhi, C. Billet +3
Dissipative solitons are remarkable localized states of a physical system that arise from the dynamical balance between nonlinearity, dispersion and environmental energy exchange.…
