200 GHz coherent wireless link using photonics-based emission

We investigated a coherent THz link at 200 GHz, with variable data rate up to 11 Gbit/s, featuring the combination of a quasi-optic UTC-PD emitter and a high sensitivity electronic receiver. This coherent link relies on an optical frequency comb generator at emission to produce an optical beat note with 200GHz separation. BER testing has been carried out using an indoor link configuration and the error-free operation is obtained up to 10 Gbit/s with a received power less than 2 μW.
