EurekAlert  September 16, 2020 An international team of researchers (Russia, UK) has developed a new approach to create electrically driven nanolasers for integrated circuits. In their approach electrical pumping is based on a double heterostructure with a tunneling Schottky contact. Plasmon-polaritons (SPPs) replace photons. The pumping happens across the interface between the plasmonic metal and semiconductor, along which surface SPPs propagate. The pumping approach makes it possible to bring the electrically driven laser to the nanoscale, while retaining its ability to operate at room temperature and the radiation is effectively directed to a photonic or plasmonic waveguide, making the nanolaser […]
