Riccardo Piccoli

Post-Doc Fellow

Riccardo Piccoli received, in July 2009, his Bachelor’s Degree in Electronic Engineering from University of Pavia (Italy), discussing the thesis: “Characterization of spectral and spatial profile of laser sources”. Then, in 2010, he received a Diploma in Piano from the Academy of Music and, finally, the Master’s Degree in Optoelectronic Engineering in July 2011 defending a thesis on tunable passively mode-locked Yb-doped fiber laser stabilized by spectral filtering supervised by Prof. G. Reali and Prof. A. Agnesi. In novembre 2011 he started a PhD related to the design, development and characterization of ultrafast passively mode-locked Yb-doped oscillators and amplifiers at the same university. He also investigated frequency down conversion in the mid-IR via parametric generation (OPG/OPA) as application of pulsed fiber lasers in MOPA configuration in collaboration with Max Born Institute (Prof. V. Petrov, Berlin). He then did a period abroad at Swansea University (Wales, Uk), Multidipliscinary Nanotechnology Center, under the supervision of Prof. S. Taccheo, where he studied Photodarkening effect in aluminosilicate highly Yb-doped fibers. This research was a part of the european project LIFT (Leadership in Fiber Technology, Grant 228587).

Since February 2015, he joined INRS-EMT as a Postdoctoral Fellow under the supervision of Prof. R. Morandotti and Prof. L. Razzari, where he is investigating phenomena in THz photonics, nanoplasmonics and quantum optics. He has recently been awarded a FQRNT Scholarship.
