Such technologies are strongly envisaged for communication applications [1]. Among the different systems already reported, the highest performances have been obtained using a combination of photonics at emission and electronic receivers [2]. As the THz bandwidth is large, the use of simple amplitude signalling can easily lead to up to >40 Gbit/s data rates [3, 4]. However, such schemes are already challenged by higher spectral efficiency (bit/s/Hz) links using quadrature phase shift keying (QPSK) or PSK-8 modulation formats and also with a required compatibility of the THz links with other services [5]. In this Letter, we present the first THz link using QPSK signalling in the sub-millimetre range with data rates of several 10 Gbit/s. Such link, associated with the development of coherent data optic fibre links in metro networks, could be used as a direct converter of a guided optical QPSK into a THz radio, for very high data rate indoor applications.Show less >
