Continuous Phase Modulations for Sub-THz Wireless Communications

We present the first experimental demonstration of a photonic-enabled wireless link using Continuous Phase Modulation in the sub-terahertz (sub-THz) frequency range. A carrier of 90 GHz is photonically generated and modulated by a 2.5Gbit/s signal with spectral efficiency of 1 (bit/s)/Hz. The receiver is placed at a distance up to 1.80 m and relies on an electronic approach.
