Siddharth Joshi received his Integrated M.Sc degree in Photonics from Cochin University of Science and Technology (India) in 2011 and a joint Ph.D degree in Optical Telecommunications from Université Pierre et Marie Curie and TelecomSud-Paris(France). During his PhD as a Marie Curie early stage researcher he worked at 3-5 lab on conception and fabrication of low chirp and low phase noise optical sources based on quantum dash nano-structures. Presently, he is working at Institut d'électronique fondamentale (France) towards development of Terahertz quantum cascade lasers. His research interests include semiconductor optoelectronic devices and optical telecommunication for short reach and access networks.
