Scientific objectives and importance of the CRC 787

Overview of the research areas and core research goals of the CRC 787.

The Collaborative Research Centre 787 "Semiconductor Nanophotonics: Materials, Models, Devices" combines three complementary areas of research aiming at the development of novel photonic and nanophotonic devices. Growth, advanced characterization of semiconductor (nano-) structures, and modeling of their electronic properties based on two of the most important families of semiconducting materials represents the backbone and is in the center of the first area. The second area focuses on fundamental theoretical and numerical modeling of optical properties of nanomaterials and of photonic devices. Design, processing and characterization of novel light emitters and amplifiers for clearly identified applications in future systems is in the center of the third area. The close collaboration between the different research areas and their mutual integration will help to explore new functionalities of nanophotonic devices and will open new dimensions of applications. One long-term goal is to realize quantum key systems that are based on q-bit and entangled photon emitters. Electrical excitation, room temperature operation, and high qbit-rate would allow for implementation in real information networks. We will also explore the limits of ultrahigh frequency vertical cavity surface emitting lasers (VCSELs, nano-VCSELs and electro-optically modulated VCSELs) and metal-cavity nano-lasers for future multi-terabus systems as well as mode-locked quantum dot lasers and optical amplifiers for ultra-high bit rate Ethernet and on chip optical clocks. Finally, we will investigate mode-locked photonic band gap crystal (PBC) lasers for use in material processing and deep UV laser diodes for applications in medical diagnostics, drug screening and rapid prototyping. The scientific objectives of the CRC 787 are the following:


  • The CRC 787 implements three complementary scientific subjects: materials, modelling and devices. Thereby the focus lies on the research of the III-V arsenide- and nitride-system as the most important materials for optoelectronics.
  • The theoretical fundaments for modeling of nano-photonic devices are established by the further development and integration of semiconductor and optical models.
  • Based on the physics and technology of nanostructures, including the modeling of electronic and nonlinear optical properties, novel nano-photonic devices are investigated, developed and characterized.



  • The CRC 787 solidifies Berlin´s position as the leading location for semiconductor and photonic sciences in Germany as well as Europe.
  • Enhancement of the networking through jointly used infrastructure.
  • Scientific transfer through collaboration with German and international industry partners.
  • Launch of new "start-up" companies
