Epitaxy - Epitaxial Growth of Layer Structures

Epitaxy is a field of professional competence offered by Jenoptik. Devices based on Jenoptik epitaxial wafers in the Al-Ga-In-As-P material system have proven their quality in numerous products. Additional to our laser products, we provide customized epitaxy services in the production of thin semiconductor layer structures, i.e. epitaxy of layer structures on GaAs wafers. In accordance to your specifications, we are able to deliver epitaxial wafers with guaranteed high-quality epitaxial growth of layer structures on 2”, 3”, and 4” wafers.

Production of epitaxial wafers

We focus on layer structures for opto-electronic components which will be the basis for your state-of-the-art devices such as


  • Laser diodes: wavelengths of 630 - 1,200 nm­
  • Surface emitters (VCSELs and VECSELs)
  • Light-emitting diodes (RCLEDs and LEDs)
  • Schottky diodes
  • Detector structures
2, 3 and 4 inch wafers
