“…The same measurement is conducted by connecting the ports of the VNA to the Q-channels of the modulator and of the receiver. A detailed explanation of this measurement is presented in [17]. Since the setup is incoherent, a phase shifter is placed after the electronic synthesizer and adjusted in a way that the maximum power is in the measured channel and therefore compensating for the total phase delay introduced in the upand down-converter.…”

In this paper, we present a 300 GHz wireless link composed of a photonic uni-traveling-carrier diode transmitter and an active electronic receiver based on millimeterwave integrated circuits fabricated in an InGaAs metamorphic high electron mobility transistor technology. The input pseudo-random binary sequence is transmitted and analyzed offline using fast analog to digital converters. The data transmission reaches 100 Gbps over a distance of 15 m. Complex modulation formats, like 32-Quadrature Amplitude Modulation and 64-Quadrature Amplitude Modulation, are successfully transmitted up to a symbol rate of 8 GBd. The system presents not only high linearity but is also capable of transmitting high symbol rates, up to 40 GBd. To the best of the authors' knowledge, this represents the highest ever reported transmission bandwidth as well as the highest spectral density symbol rate product for transmissions with center frequency in the terahertz band. Thus, the usage of such links in future bandwidth-hungry applications like data centers, data showers, front-and backhaul is proven feasible.
