FCC-compliant millimeter-wave ultra-wideband pulse generator based on optoelectronic oscillation

摘要

We report a photonic scheme to generate a millimeter-wave ultra-wideband (MMW-UWB) pulse based on optoelectronic oscillation (OEO). Normally, a millimeter-wave signal source is essential for the generation of a MMW-UWB pulse. The key novelty of our work is that no millimeter wave signal source is required. The MMW-UWB pulses are directly generated by truncating an OEO signal into pulses. The principle behind the proposed scheme is analyzed in detail. A proof-of-concept experiment shows that the generated MMW-UWB pulses fit the Federal Communications Commission (FCC) spectral mask very well. (C) 2019 Optical Society of America
