Micro-/Nano-structure fabrication is a key challenge faced in many areas of photonics, nanotechnology, and biology. Light Extraction Aps has developed low-cost, scalable micro-/nano-fabrication methods for both industry and research purpose.


Light Extraction Aps provides micro-/nano-patterning services and wafer products for the applications of, but not limited to

  • Enhance the light extraction efficiency of LEDs;
  • Improve the light absorption of solor cells;
  • Modify the surface properties of different materials;
  • Serve as nanoimprint mold;
  • Other applications.


Micro-/nano-structures developed by our methods can have a feature size from tens of nanometers to micrometers, periodic or stochastic, on differnet materials (Si, SiC, sapphire, GaN, etc). Light Extraction Aps also offers customized solutions based on state-of-the-art cleanroom facilities.
