Structured Illumination at the Nanoscale

Structured Illumination at the Nanoscale

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

Activities

  • Development of structured light illumination platforms using nano- and µLEDs and lasers
  • Integration of these platforms into systems like a super-resolution microscope: separately switchable nanoLEDs in an array allow to control the light at the nanoscale with a spatial precision below the wavelength of light and possibly even below the diffraction limit
  • Support EU projects SMILE/SmartFire

Competences/Services

  • Epitaxy of III-nitride based LEDs
  • Processing to nano- and µLEDs and arrays
  • Characterisation of nano light sources
  • Hybride integration of LED chip with CMOS microelectronics
  • System integration (guiding of light on the chip, housing and software)
