Variable electro-optic shearing interferometry for ultrafast single-photon-level pulse characterization
StanisÅaw Kurzyna, Marcin JastrzÄbski, Nicolas Fabre +3
Despite the multitude of available methods, the characterisation of ultrafast pulses remains a challenging endeavour, especially at the single-photon level. We introduce a pulse ch…

Spectrum-to-position mapping via programmable spatial dispersion implemented in an optical quantum memory
Marcin JastrzÄbski, StanisÅaw Kurzyna, Bartosz Niewelt +3
Spectro-temporal processing is essential in reaching ultimate per-photon information capacity in optical communication and metrology. In contrast to the spatial domain, complex mul…

Experimental implementation of the optical fractional Fourier transform in the time-frequency domain
Bartosz Niewelt, Marcin JastrzÄbski, StanisÅaw Kurzyna +4
The fractional Fourier transform (FrFT), a fundamental operation in physics that corresponds to a rotation of phase space by any angle, is also an indispensable tool employed in di…
