Bio
Filip Sośnicki is a researcher at the Faculty of Physics at the University of Warsaw, where he works at the Quantum Photonics Lab led by Dr. Michał Karpiński. There, in 2016, he graduated with an MSc (with distinction) in the theoretical physics by numerically studying electro-optic time lensing of light. Later, in 2023, he defended his doctoral thesis (with distinction) on the topic of coherent shaping of quantum light pulses in the spectro-temporal degree of freedom by developing an electro-optic experimental platform for time lensing.
In years 2019-2022 he was a PhD student in the FNP First TEAM project entitled “Phase-only shaping of light pulses for applications in quantum technologies”. Since 2020 he is the principal investigator in the PRELUDIUM project on “Characterization of high-resolution single-photon time-tagging measurement based on time-to-frequency mapping” funded by the National Science Center of Poland.
He actively participates in the academic community, he is a member of Optica, SPIE, EPS, IEEE Photonics, and the Student Association of Optics and Photonics - KNOF. In particular, in years 2019-2022, he was the KNOF's treasurer. He cares about students – he was awarded by the Dean of the Faculty of Physics UW for outstanding teaching classes.
He supports open-source community by designing 3D-printing models of optical lab supplies and equipment, which he publish here (link).
