i-FPS - Compact, high-performance and highly integrated faint pulse source at 850 nm
Project period: 02/2022 - 12/2024
Funding: Funded by the Federal Ministry of Economics and Climate Protection (BMWK) with the project management organizationGerman Aerospace Center e.V. Space Administration (DLR)
The aim of the overall project is the realization of a compact photon source with attenuated pulses, a so-called Faint Pulse Source (FPS), for the generation of quantum keys with a high key rate in satellite-based communication. The FPS architecture to be developed should enable a new generation of an FPS that is characterized by GHz photon rates, compactness, scalability and high key rates under all security-relevant aspects.
The research objectives focus on the electronics development and RF-compatible module integration of an FPS that meets the requirements for satellite applications. In addition to implementing the high-frequency control electronics of the VCSEL diodes, key issues include mechanical and thermomechanical robustness as well as miniaturization and weight minimization.
To solve the complex task for the hardware platform, a developed and verified multilayer ceramic technology is used. The control of the VCSEL diodes is to be realized on a fast FPGA platform.
