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 ...

Diplomatische Strategien der Regentin Christine Charlotte von Ostfriesland (1665-1690)
The dissertation project examines the custodial regency of Princess Christine Charlotte in East Frisia from 1665 to 1690, which was marked by domestic conflicts interwoven with external conflicts and interests. While the regent saw herself as sovereign and considered the form of government as princely, the estates saw themselves as free and ...

Automotive VLC - Open Hardware Project Kommunikation mit sichtbarem Licht (1. Projektphase)
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 ...

Heterogene Widerstandskulturen: Sprachliche Praktiken des Sich-Widersetzens von 1933 bis 1945
Despite permanent danger to their lives, numerous individuals decided to resist during German National Socialism. There actions were diverse and not always spectacular, but they always found expressions in individual, heterogeneous communicative practices. The DFG-funded project "HetWiK" (Heterogeneous Cultures of Resistance: Communicative ...

TRR 142 - Widely non-defenerate stimulated two-photon emission in semiconductors (A07)
Two-photon emission is a process in which optical transitions occur through the simultaneous emission of two photons. Here, we will focus on experimental and theoretical studies of widely non-degenerate two-photon emission stimulated by femtosecond pulses. Similar to nonlinear optical absorptions, such processes are expected to be massively ...
