In-building Optical Wireless Positioning Using Time of Flight
Autor: Christoph Kottke, Ziyan Ma, Sepideh Mohammadi Kouhini, Volker Jungnickel
Publikováno v: Optical Fiber Communication Conference (OFC) 2023.
We present a LiFi positioning and communication system based on the ITU-T G.9991 standard. Accuracies as low as 3 cm in x,y,z direction have been achieved, utilizing an optimization approach for the LED behavior.

56 GBaud PAM-4 Direct Detection with High-Speed Avalanche Photodiodes
Autor: Tobias Beckerwerth, Christoph Kottke, Volker Jungnickel, Ute Tropenz, Martin Möhrle, Patrick Runge, Martin Schell
Publikováno v: Optical Fiber Communication Conference (OFC) 2023.
We demonstrate 56 GBaud PAM-4 transmission by using a high-speed waveguide avalanche photodiode (WG APD) and an electro absorption modulated laser (EML). Compared to a PIN photodiode, the WG APD reduces the power budget in a B2B setup by 6 dB.

Coherent LiDAR Prototype Based on 2D MEMS Mirror Scanning
Autor: Sarah Cwalina, Christoph Kottke, Norman Laske, Volker Jungnickel, Ronald Freund
Publikováno v: Optical Fiber Communication Conference (OFC) 2023.
We present a new coherent LiDAR prototype with two-dimensional micro-electro-mechanical-system scanning and walk-off mitigation capability. We address the linearization challenge of the FMCW transmitter, the scan-capture-synchronization and pro-vide
