DTU Fotonik works with all areas of photonic engineering, including a strong focus on optical communications. We are hereby announcing a PhD position within the topic of advanced space-division multiplexing technology in optical communications. 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 has been 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. The project will start within the winter semester, 2019.

Responsibilities and tasks 
As communication capacity of the standard single mode fibre is approaching its fundamental physical limit, employing space (i.e. orthogonal spatial modes or multiples cores of optical fibres) as a new 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. This PhD project will aim at exploring the most advanced spacedivision multiplexing (SDM) technologies to achieve capacities beyond 10 Pbit/s per fiber and 1 Pbit/s per laser 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. Within the PhD project, the PhD student will explore orbital angular momentum (OAM) modes and higher order modes (HOMs) and will study how electrical/optical signal processing can enhance their system performance in record-breaking experiments.

The PhD project will have strong synergies to other activities within the SPOC centre, for example those on multi-core fibres, Sibased OAM MUXs/DEMUXs and ultrafast optical signal processing schemes, e.g. ultra-wideband phase conjugation and time lenses. It is expected that the PhD student will benefit from collaboration with these activities to enhance the outcome of the PhD project.

Candidates should have a master's degree in engineering/physics or a similar degree with an academic level equivalent to a master's degree in engineering/physics. Good communication skills in written and spoken English are required.

Approval and Enrolment 
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide

The assessment of the applicants will be made by the SPOC centre leader Professor Leif Katsuo Oxenløwe and Professor Toshio Morioka.
