We have several postdoc researcher positions and graduate student positions open.

Our current research interests include:

  • Micro- and nano-scale lasers
  • Novel perovskite light sources
  • Topology in Hyperbolic Metamaterials and non-Hermitian optical systems
  • NanoLEDs for high speed optical communication
  • Neuromorphic photonics
  • Photonic integrated circuits
