QuantumFrontiers Research Topics

Structured Illumination at the Nanoscale

Development of structured light illumination platforms using arrays of nano-/µLEDs or lasers and their system integration.

Contributions to QuantumFrontiers

  • Development of nanolight (e.g. µLEDs, laser diodes) for the control of electromagnetic fields at the nanoscale and demonstration of controlling light fields with a precision of 5 nm
  • Design and fabrication of vertical emitting lasers like VCSELs with advanced coherence control, particularly in the UV/blue spectral region 
  • Development of hybrid photonic-plasmonic waveguides for nanoscale light focusing as a potential platform for the manipulation of quantum systems
  • Integration of structured light illumination platforms into systems like a super-resolution microscope or atom and ion chip traps, whereby separately switchable nanoLEDs in an array allow control of the light at the nanoscale with a spatial precision below the wavelength of light and possibly even below the diffraction limit
  • Demonstrating proof-of-principle high-TRL systems based on µLED technology, which have high market potential and motivate spin-off companies
     

Collaborative Innovation

  • Simulation and fabrication of High Contrast Gratings for VCSELs (Kroker, Waag TU Braunschweig)
  • TEM characterisation of epitaxial material for nano light sources (Etzkorn, Waag TUBS)
  • Electron beam lithography for photonic crystals and high contrast gratings (Siegner PTB, Kroker, Waag TUBS)
  • Integration of µLED and laser arrays with CMOS to control large arrays with high density and small pixel sizes and pitches (Issakov, Waag TU Braunschweig)
  • Integration of laser diodes and integrated photonic circuits (PICs) for controlling light on a chip (Waag, Kroker TUBS, Mehlstäubler PTB)
  • Development of tunable and active metasurfaces for control of EM energy at the nanoscale (Kroker TUBS)
  • Laser printing of nanoparticles for the realization of novel micro-optomechanical devices (Chichkov LUH)
