PhD Scholarship 1 in Multidimensional Fiber-optical Communications

Chalmers University of Technology is pleased to invite applicants to apply for a PhD position in mathematical analysis. Successful candidate will have funding to work and study for four years in Sweden. Applications are welcome before March 17, 2019.

At the department of Electrical Engineering research and education are performed in the areas of Communication and Antenna systems, Systems and Control, Computer vision, Signal processing and Biomedical engineering, and Electric Power Engineering. Our knowledge is of use everywhere where there is advanced technology with integrated electronics. We work with challenges for a sustainable future in society of today, for example in the growing demands concerning efficient systems for communications and electrifying.

We offer a dynamic and international work environment with about 200 employees from more than 20 countries, and with extensive national and international research collaborations with academia, industry and society. The department provides about 100 courses, of which most are included in the Master's Programs "Biomedical Engineering", "Electric Power Engineering", "Systems, Control and Mechatronics" and "Communication Engineering".

The Internet is powered by optical fiber communications, with the world's data flowing through drawn pieces of glass, each slightly thicker than a human hair. While technological advances have enabled six orders of magnitude increase in throughput over the last half century, we are rapidly approaching the so-called capacity crisis, where throughput will flatten out, but demands increase unabated. This project will study the hypothesis to what extent optical fibers still hold large and untapped potential to achieve unprecedented data rates, both theoretically and practically. The crux is considering the available physical dimensions in a joint manner, as opposed to independent. In this project, we will enter this uncharted territory with two ambitious goals: to characterize the full-dimensional capacity of an optical fiber and to develop a spatial-spectral super-channel demonstrator to show significant throughput gains over current systems. Four PhD students and two postdoctoral researchers are recruited. See the joint announcement for all openings in the project.

You will be part of the Fiber-Optic Communications Research Center (FORCE) at Chalmers, bringing together researchers in communications, photonics, electronics, and networking to solve hard problems in optical communications through a cross-disciplinary approach. The collaboration bridges traditional discipline boundaries and includes the whole chain from components to networks, from analysis to experiments. Collaboration with external partners, both in industry and academia, is also essential.

Major responsibilities

You will participate in research as outlined above and will be developing information-theoretic methods to estimate and bound the full-dimensional channel capacity. Your work will require collaboration with the experimental parts of the work (as you will process experimental data to generate models and validate theoretic results) as well as the signal-processing parts (as your results will guide the development of transmitter and receiver algorithms). You are expected to publish your results in major journals and conferences. The appointment offers great opportunities to qualify for further research positions within academia or industry as we have numerous ongoing collaborations with the leading groups internationally.

The position as a PhD student is a full-time temporary employment, limited to a maximum of four years, plus teaching and other departmental duties. A monthly salary is paid. There are no tuition fees for PhD studies at Chalmers.


The applicant should have a Master’s degree in Applied Mathematics, Engineering Physics, Electrical Engineering, or equivalent, with excellent knowledge of digital communications and signal processing. High grades in the core courses are required (we generally accept only the top 10% of students, from well-ranked universities). Skills in mathematical analysis are essential, particularly transforms, probability, and differential equations. Experience in optical communications is not required, but you should have an interest in applying your skills to optical systems. Good communication skills and fluency in English are essential, as are good programming skills. Previous experiences in research, publications, and teaching are also advantageous.

Chalmers offers a cultivating and inspiring working environment in the dynamic city ofGothenburg. Read more aboutworking at Chalmersand ourbenefitsfor employees.
