Abstract
We present the implementation of a PIC-based nonlinear frequency division multiplexed transmission system in which spectrally overlapping channels are stitched together without frequency guard bands to obtain a seamless spectrum. To coherently combine the channels with partial overlaps, the channels are generated using a comb source whose pulse repetition rate is synchronized with the clock used to generate the electronic signals. After that, all channels are linearly multiplexed using a PIC in which the delay and phase of all the optical paths are balanced and dynamically corrected. The proposed solution can fill large optical bandwidths while keeping the computational complexity to that of independently processing multiple low bandwidth channels.

Alvaro Moscoso Martir received the MSc in Telecommunications Engineering from Malaga University (Spain) in 2008 and the PhD in Microwave Engineering from Malaga University in 2013. During his PhD he was focused on the design and evaluation of ultra-wideband microwaves components and systems for multilayer technologies. In 2014 he joined the Institute of Integrated Photonics at RWTH Aachen as a postdoctoral researcher and later in 2021 he was promoted to senior scientist with a permanent position. His research interests are Ultra-wideband microwave components and systems, opto-electronic integration and assembly, packaging of silicon photonic chips, integrated photonic circuits, optoelectronic modulators and opto-electronic transceivers for Datacom and Telecom applications.
