PIN photodiode emitters for 32 GBd 16QAM wireless link at 300 GHz

We demonstrate a wireless data link at 300 GHz employing a broadband PIN photodiode as the emitter. With a symbol rate of 32 GBd and QPSK modulation error-free transmission at a gross data rate of 64 Gbit/s is achieved. For 16QAM modulation, forward error correction enables a net data rate of 100 Gbit/s, which is among the highest values reported so far.
