In this paper we describe our work on silicon photonics based advanced transceivers. This includes the realization of 100 GBaud OOK and duobinary transceivers and 56 GBaud PAM-4 transmitters for datacenter applications, 40 GBaud 16-QAM coherent receivers for metro and 20GBaud PAM-4 transceivers for access networks. Analog radio-over-fiber transceivers for next-generation 5G wireless access will be described as well, covering carrier frequencies ranging from 3.5 GHz to 28 GHz. These transceivers rely on both advanced photonic and electronic integrated circuits.
In order to realize a fully integrated transceiver, the III-V laser source needs to be integrated as well. For this purpose we are developing a novel integration strategy: micro-transfer printing. In this talk I will elaborate on the underlying concepts as well as discuss first realizations of transfer printed III-V-on-silicon opto-electronic components.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
