FOR 2863 - Active THz Transceiver Components
Compared to radios operating at purely optical wavelengths or RF/microwave frequencies, the combination of extremely high absolute bandwidths and high relative bandwidths in the THz frequency regime, paired with the severe performance limitations of technologies operating in the so-called "THz-gap", imposes unique challenges on modern digital ...

NyPhE - Nyquist Silicon Photonics Engine
Exponentially growing data traffic around the world leads to increasing demand for high speed server communication in data centers. Future communication systems have to reach data rates well beyond 100 Gbits/s and low power dissipation is becoming an increasingly important characteristic. Therefore, novel transceiver concepts are required to enable ...

FOR 2863: MEtrology for TERAhertz COMmunication (Meteracom)
For the advance of THz communication systems, the capability to perform precise measurements is crucial. Metrology at THz frequencies is however still in its infancy and as of today it only covers detector calibration for characterization of ultrafast devices and measurement uncertainty analysis of different spectrometer types available at THz ...

SPP 2111 - Ultra-Wideband Photonically Assisted Analog-to-Digital Converters (PACE) - Phase 2
Silicon-based analog-to-digital converters (ADCs), which operate at sampling rates in the double-digit GSa/s range, are state of the art today. Although these converters now operate at unprecedented sampling rates, the effective number of bits (ENOB) and analog bandwidth are improving only slowly. A major obstacle to further improvements in ...

SPP 2111 - PONyDAC II - Precise Optical Nyquist Pulse Synthesizer DAC
Fast digital-to-analog converters (DAC) are indispensable components for modern signal processing systems. Bandwidth and effective number of bits (ENOB) are important metrics for the performance of DACs. At the same time, those parameters constitute a trade-off in the design of a DAC: The more broadband the DAC, the less typically the ENOB. This is ...

Automotive VLC - Open Hardware Project Visible Light Communication (1st project phase)
Light Emitting Diodes (LEDs) are becoming more and more the primary source of illumination in different indoor and outdoor environments. Besides their illumination function, their ability for fast switching enables a new kind of application, namely Visible Light Communication (VLC). VLC uses the multi-THz wide, license free visible light bands of ...

Visible Light Sensing
Light-emitting diodes (LEDs) are increasingly being used as a primary light source both indoors and outdoors. In addition to their role as efficient lighting, LEDs also offer potential for new applications in sensor technology like visible light sensing (VLS) thanks to their high switching speed. VLS uses several terahertz (THz) of license-free ...

Blind radar for visual impaired people
The aim of this project is to develop an innovative assistance system for visually impaired people. It uses a 120 GHz FMCW radar that detects obstacles that are outside the range of a conventional cane. To make use as intuitive as possible for users, the radar system is integrated into a handy device. A special lens ensures that only objects within ...
