One of the biggest challenges in photonics is developing small, energy-efficient coherent light sources that can be integrated directly onto a chip. Traditional lasers are often inefficient in power usage and too bulky for compact devices. This project aims to develop nanoscale lasers using atomically thin 2D materials. It will explore ways to control the polarization of light in these lasers, as polarization modulation can be achieved faster and with less power than conventional intensity modulation. The research will advance our understanding of 2D materials and their integration into photonics. On-chip integrated nanolasers have the potential to significantly improve speed and efficiency in telecommunications, artificial intelligence, and cloud computing. The work will be carried out at the University of Eastern Finland, Joensuu, in collaboration with Aalto University, University of Turku, ETH Zürich and PSI (Switzerland), University of St. Andrews (UK), and LMU Münich (Germany).
