PhD scholarship in Integrated Photonic Chips for Space-Division Multiplexing: Multi-Mode Generators, Processors, Receivers

DTU Fotonik works with all areas of photonic engineering, including a strong focus on optical communications. We hereby announce a PhD position within a topic of integrated photonic chips for space-division multiplexing: multi-mode generators, processors, receivers. This project is part of the centre of excellence Silicon Photonics for Optical Communications (SPOC) funded by the Danish National Research Foundation. The SPOC centre was established to aim at significantly advancing the state-of-the-art in ultra-high capacity optical communications and this PhD project will be at the heart of this activity.

Responsibilities and qualifications
As the communication capacity of standard single mode optical fibres is approaching its fundamental physical limit, employing space (i.e., orthogonal spatial modes or multiples cores of optical fibres) as a new and the last multiplexing dimension, so called space-division multiplexing (SDM) has proven to be an effective way to further push the communication capacity in order to accommodate the ever-increasing capacity demands in the future. In SPOC, we have been exploring the most advanced SDM technologies to achieve capacities towards 100 Pbit/s and beyond per fibre based on integrated optical transmitters, mode multiplexers/ demultiplexers (MUXs/DEMUXs), and receivers in order to substantially decrease power consumption per bit and space per bit. This PhD project is aimed at developing photonic chips for SDM such as multi-mode generators, processors, receivers, which will be utilized in SDM system demonstrations. This includes mode multiplexers/demultiplexers, SDM-switches and modulators. The project will also plan to develop all-optical MIMO schemes based on integrated photonics for short-reach and/or DMD (differential mode delay)-managed transmission systems. The PhD project will start in early spring, 2022.

The PhD project will have strong synergies with other activities within the SPOC centre, for example those on ultimate capacity fibre design, ultrafast optical signal processing, and information theory/advanced coding. It is expected that the PhD student will benefit from collaboration with these activities to enhance the outcome of the PhD project.

You must have a two-year master's degree in engineering/physics (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree in engineering/physics. Knowledge about designs, fabrication, and characterization of integrated photonic chips is preferred.
