TRR 142 - Compact high performance photon pair source using ultrafast hybrid modulators based on CMOS and LNOI (C11*)

The project aims to study and demonstrate miniaturized sources of decorrelated photon pairs with high repetition rate. The goal will be achieved by jointly integrating high-bandwidth electro-optic modulators, and a specifically tailored parametric down-conversion (PDC) section, both in a lithium-niobate-on-insulator (LNOI) platform. To obtain ...

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 ...

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 ...
