300 GHz-band 50 Gbit/s dual channel link using industrial silicon photonics technology

We demonstrate the use of an industrial silicon photonics photodiode towards indoor THz links in the 300 GHz band. The devices are presented and two links are reported: the first one in a single channel operation QPSK-25 Gbit/s signaling and the second one using a dual channel configuration, 260 and 280 GHz, reaching 50 Gbit/s. In each case, the detection is done using a III-V GaAs Schottky-based sub-harmonic mixer.
