With the format “Research in Brief,” the Ferdinand-Braun-Institut (FBH) presents current results and developments from its research activities. The contributions concisely summarize selected work from the past three months and group them by topic.
The selection is based on the research news published by FBH on its website on a biweekly basis. These articles provide insights into new scientific results from the institute’s various fields of work and illustrate the continuous progress of its research.
1. Integrated Quantum Technology
Laser system for excitation of fluorescent light sources on a CubeSat
We have developed a compact fiber-coupled laser source emitting at 698 nm to excite a single-photon emitter in low Earth orbit. Built and qualified faster and cheaper compared to a traditionally certified payload, this system embodies the “new space” developing philosophy.

Double helical optical antennas for direct coupling to on-chip waveguides or quantum emitters
We’ve developed, to the best of our knowledge, the world’s smallest chip-integrated double helical antennas that are sensitive to the circular polarization state of visible to telecom light. The antennas are written directly using a focused electron beam in a 3D nanoprinting process.

2. Photonics
Far-UVC micro-LEDs for enhanced fiber coupling
We have developed far-UVC LEDs with a micrometer-structured surface design that improves light extraction and enables efficient fiber coupling. This advancement supports disinfection applications in hard-to-reach areas, including human body cavities.

780 nm mode-locked monolithic diode laser for two-photon polymerization
We have developed a compact, mode-locked monolithic diode laser emitting at 780 nm that delivers ultrashort, high-power pulses. It enables precise micro-3D printing via two-photon polymerization, achieving quality comparable to or even better than large Ti:sapphire laser systems.

3. III/V-Electronics
Precise radio frequency transistor testing with automation and machine learning
Our new optically guided probing method and image-analysis machine learning algorithms enable precise, fully automated on-wafer measurements of RF transistors. This approach improves probes’ position accuracy below 2 µm in measurements up to 50 GHz.

Realtime power monitoring of wireless communication systems for high data rate links – first results
First laboratory results demonstrate that real-time power monitoring at component level enables significant energy savings in high data-rate wireless systems. Dynamic adjustment of supply voltages reduced overall power consumption by 14.5 % without impairing performance.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
