FBH extends its basic network-oriented approach to work beyond the insitute by intensely cooperating with various universities. With its Joint Labs, the insitute closely dovetails basic- and application-oriented research:
Joint Lab GaN Optoelectronics
This Joint Lab develops innovative light emitters based on group-III nitrides, especially light-emitting diodes (LEDs) for the near and far UV spectral range and diode lasers emitting in the blue-violet and ultraviolet spectral range. Partner of the FBH within this Joint Lab is the Faculty of Experimental Nanophysics and Photonics led by Prof. Dr. Michael Kneissl at the Institute of Solid-State Physics at Technische Universität Berlin.
Joint Lab Quantum Photonic Components
Here, the research focuses on the development of electro-optical components and hybrid micro-integrated modules that provide coherent radiation required, e.g., for the implementation of quantum optical sensors or quantum computers based on cold ions or neutral atoms. Emphasis lays on narrow and ultra-narrow linewidth lasers also relevant for coherent free-space communication and laser metrology. The activities include R&D for space applications.
The Joint Lab was established in 2008 at FBH to foster co-operation with the Optical Metrology Group at Humboldt-Universität zu Berlin, at that time under the name Joint Lab Laser Metrology. Now renamed, it serves as the nucleus of the Integrated Quantum Technology research area at FBH, which was set up in 2019.
Joint Lab Integrated Quantum Sensors
This Joint Lab cooperates with the Optical Metrology Group at Humboldt-Universität zu Berlin. Research focuses on the development of integrated quantum sensors using high-precision spectroscopy techniques with atomic or molecular ensembles either at room temperature or, by laser cooling, near absolute zero. Here, the intrinsic properties of quantum mechanical states and their precise manipulation with laser light are exploited to realize instruments for highly accurate measurements of physical quantities such as frequency, accelerations, electric or magnetic fields. The activities include R&D for space applications.
Joint Lab Diamond Nanophotonics
The Joint Lab Diamond Nanophotonics cloosely cooperates with the Physics Department at HU Berlin. The research focuses on nanostructured diamond systems and materials and aims at developing novel concepts for guiding, catching, and manipulating light on the nano- and microscale, and enabling strong light–matter interaction in diamond with the goal to efficiently couple, or more precisely, to entangle single quantum memories with single photons. Quantum memory–photon entanglement as well as quantum gates will then build the basis for the implementation of future quantum communication platforms that are more secure and versatile than present classical schemes.
Joint Lab Terahertz Electronics
This Joint Lab closely collaborates with Prof. Dr. Viktor Krozer, chair of Goethe Leibniz Terahertz Center at the Department of Physics of Goethe Universität Frankfurt am Main (GUF) - his professorship is jointly sponsored by GUF and FBH. In the frame of this cooperation, terahertz technologies and complex system-on-chip concepts for millimeter wave systems are developed, satisfying the demand for an ever faster communication infrastructure, more powerful imaging methods, and complex as well as flexible circuits and systems.
Joint Lab Power Electronics
This Joint Lab is a cooperation of the FBH with Prof. Dr.-Ing. Sibylle Dieckerhoff, who is responsible for the Power Electronics Field of Expertise at the Institute for Energy and Automation Technology at TU Berlin. This lab forms the inerface between GaN semiconductor technology and highly efficient energy converter systems. This way, energy-efficient, compact, and capable electronic energy converters shall be available for a great variety of application in the future - from communication and automotive technology to the conversion of solar energy.
Joint Lab BTU-CS – FBH Microwave
Within this Joint Lab, the FBH closely cooperats with Prof. Dr. Matthias Rudolph, who holds the Ulrich-L.-Rohde Chair of RF and Microwave Techniques at Brandenburg University of Technology Cottbus-Senftenberg (BTU-CS). In the frame of this collaboration, transistor models are developed used to determine the electrical and thermal behavior before their realization. Another focus is on the development of particularly rugged low-noise amplifers based on FBH GaN-HEMT technology.
