"Energy Efficiency Modulators and Frequency Combs for On Board Optical Communications"

Kambiz Jamshidi, Assistant Professor, Technical University Dresden, Germany

Energy consumption and ecological impact of ICT section is growing rapidly. Communication networks, computers and data centers share this energy consumption. In order to address this issue, various solutions have been pursued in hardware, architecture, and software levels so far. In Dresden, a collaborative project, funded by German Research Foundation, named Highly Adaptive Energy-efficient Computing (HAEC) has been started to research towards technologies to enable computing systems with high energy efficiency without compromising on high performance.

In this talk, initially a brief overview about the ongoing activities of integrated photonic devices group in TU Dresden will be presented. After that, the frequency comb and the reverse biased modulator, to be used for on-board optical communications in HAEC, will be discussed based on the numerical modeling of these devices using a system model approach. Tradeoffs of various modulator designs (slow light as well as ring structures) in terms of bandwidth, optical energy efficiency, and electrical energy efficiency will be described. Finally, our recent activities to design energy-efficient frequency comb generator on silicon will be presented.
