Postdoctoral or PhD student position in Spatial division multiplexing

The Department of Microtechnology and Nanoscience (MC2) focuses on research, innovation and education within the fields of future electronics, photonics, bio- and nanosystems. A close collaboration with Swedish and international partners within academy, industry and society enables scientific excellence and creates an innovative environment. In addition to the 200 researchers and PhD students, MC2 houses a cleanroom for micro- and nanofabrication with the latest equipment.

Information about the research
Optical fiber communication systems constitute the backbone of Internet. In this project, we will analyze and demonstrate concepts to reach substantially higher transmission throughput than in today’s optical communication systems. This is essential, as the currently used technology approach, using single-mode optical fibers, is expected to be exhausted within the next decade, due to fundamental capacity limits of a single transmission channel. We will leverage our expertise in optical transmission experiments as well as in information theory, coding and digital signal processing to investigate, both theoretically and experimentally, concepts relying on spatial-division multiplexing (SDM). This has emerged as the most viable approach to significantly increase capacity by encoding data in several cores and/or modes of a single fiber. Specifically, we will establish a physical understanding of coupling among modes/cores in optical fibers supporting several modes or cores. This knowledge will serve as a basis in order and design novel modulation formats and coding schemes taking advantage of this new spatial dimension. We will further design and implement a spatial – frequency superchannel that allows important scaling advantages as well as being compatible with monolithic integration for cost and energy efficiency. We will bring this together in transmission systems experiments using SDM hardware to reach unprecedented transmission performance. 

The project is cross-disciplinary and involves two different departments at Chalmers; the Photonics Lab at Department of Microtechnology and Nanoscience and the Communication Systems Group at the Department of Signals and Systems. The project will benefit from the prolific research environment in the Fiber-Optic Communication Research Centre (FORCE).

Major responsibilities

Postdoctoral position:
Your major responsibility as postdoc is to perform your own research in a research group. The position also includes teaching on undergraduate and master's levels as well as supervising master's and/or PhD students to a certain extent. Another important aspect involves collaboration within academia and with society at large. The position is meritorious for future research duties within academia as well as industry/the public sector.

PhD student position:
The person filling this position will participate in research as outlined above and will be conducting experimental work supported by numerical simulations. The appointments offer an opportunity to qualify for further research positions within academia or industry. Included in your work is also to some extent taking part in the supervision and teaching of students.

Position summary

Postdoctoral position:
The position as a Post-doctoral fellow is a full-time temporary employment, limited to a maximum of two years.

PhD student position:
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.

Qualifications

Postdoctoral position:
To qualify for the position of postdoc, you must have a doctoral degree in Engineering Physics, Electrical Engineering or similar; the degree should generally not be older than three years.
