## Description

- description: Optoelectronics is a valuable solution to scale up wireless links frequency
    to sub-THz in the next generation antenna systems and networks. We propose an
    innovative, low-power consumption, small footprint building block for 5G and 6G
    new radio wireless transmission allowing broadband capacity (e.g., 10-100 Gb/s
    per link and beyond). We pioneer the first wireless datalink based on graphene,
    reaching setup limited sub-THz carrier frequency and multi-Gbit/s data rate using
    a graphene-based integrated optoelectronic mixer capable of mixing an optically
    generated  ~100 GHz reference oscillator with a baseband electrical signal. We
    report >96GHz optoelectronic bandwidth and -44 dB upconversion efficiency with
    a footprint significantly smaller than those of state-of-the-art photonic transmitters
    (i.e., <0.1 mm2). This paves the way to the development of novel arrayed-antennas
    for millimeter-wave technology relying on a new approach which takes advantage
    of optics. These results have been achieved thanks to an integrated-photonic technology
    based on wafer-scale high-mobility graphene.
