Korevaar, C.W. (author), Boschma, J.J. (author), den Breeje, R. (author), Ebert, J. (author)Optical feeder links (OFLs) benefit from the vast amount of bandwidth available in the THz-regime of the electro-magnetic spectrum, and could enable future terabit-per-second satellite systems. This study assesses the end-to-end performance of analog coherent OFLs for digital video broadcasting (DVB) applications, employing phase modulation (PM)...conference paper 2022

(author), van de Pol, M. (author)Optical satellite communications is a maturing technology to enable word-wide access to high throughput internet. In the past years a lot of effort has been taken to increase the applicability and the TRL of this technology. In collaboration with industry, TNO initiated several developments for space and ground technologies. Many of these...conference paper 2021
