A recent Cluster publication with participation of Associate PI Wolfram Pernice paves the way for controllable integrated photonic circuits. By using heterogeneous integration of electroluminescent, semiconducting carbon nanotubes into hybrid two dimensional – three dimensional (2D-3D) photonic circuits, the authors overcome existing challenges of emerging photonic information processing systems. The paper titled “An electroluminescent and tunable cavity-enhanced carbon-nanotube-emitter in the telecom band” was published in the renowned scientific journal nature communications.
