Wireless Transmission of Millimeter Waves Generated by L-band InAs/InP Quantum-dash Laser

Wireless transmission of unmodulated 28, 38, and 60GHz millimeter-wave (MMW) sub-carriers, generated by L-band quantum-dash laser-based comb-source, is investigated in terms of RF-characteristics. Low-frequency MMWs showcased ~4 to 5dB/m power-attenuation and ~−2 to −3dBc/Hz/m phase-noise degradation, while the 60GHz signal exhibited twice these values.
