We will conduct data transmission experiments using intensity modulation and direct detection, as well as coherent schemes, with the goal of transmitting symbol rates beyond 150&nbsp;GBd. We will also use the modulators developed in HDLN to convert ultra-broadband electrical signals to the optical domain and perform photonic-assisted signal processing using the architecture developed in the project \u201cTeraSlice\u201d. To this end, we have started to design novel approaches to couple ultra-broadband electrical signals (bandwidths of several 100 GHz) to integrated optical devices. In this context, we explored 3D printed freeform THz structures that were fabricated by multi-photon lithography and subsequent metal coating (see Figure below). This work led to the following publication, which is available on arXiv:<\/p>\n\n\n\n<p>P.
