The Department of Microtechnology and Nanoscience 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 project
In the area of communication we implement new modulation formats to achieve higher spectral efficiency in optical communication channels, thereby increasing capacity. Ultralow noise optical amplifiers are investigated as they allow a significant increase of throughput in long-haul transmission. The more device-oriented research deals with lasers satisfying requirements for optical interconnects in terms of speed and power consumption. The work is coordinated in the Fibre Optical Communications Research Centre (FORCE), see

This research project deals with the integration of optical functions in a compact format is essential in future optical systems in order to reduce cost and footprint while at the same time increase performance and scalability to large volumes. In this project, we are developing the silicon integration technology for transmitters in both short- and longer reach optical interconnects (to be used e.g. in data centers or supercomuters) using multi-wavelengths transmitters based on VCSELs and nonlinear ring resonators. Some components will be fabricated in our in-house clean room and others will be designed and outsourced to an outside foundry. The research will deal with the performance characterization of components, sub-systems, and full system experiments.

We are now seeking an innovative self-motivated person that will be able work independently as well as in larger teams.

The project is funded by the Swedish research council (VR) and is a collaboration with Technical University of Denmark.

Major responsibilities
The person filling this position will participate in research as outlined above and will be conducting mainly experimental work and supporting it with numerical simulation work. The work includes the analysis and characterisation of devices, concepts, sub-systems, and full systems for mid-reach optical interconnects. The appointment offers an opportunity to qualify for further research positions within academia or industry. Included in the work is also to some extent taking part in the supervision and teaching of undergraduate students as well as departmental duites.

Position summary
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.

Applicant should have a Master’s degree (or equivalent) in Photonics, Electrical Engineering, Engineering Physics, or similar, with a strong background in optical communications or optoelectronics. Excellent team-working skills, presentation skills, and fluency in English are required. Chalmers offers Swedish courses. As important merits will be considered knowledge of optical devices and their fabrication and experience with optical tranmission experiments. Matlab and other simulation software, teaching experience, and publications.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
