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

The Photonics Laboratory at the Department of Microtechnology and Nanoscience, with about 30 members, conducts application oriented research in optoelectronics and fiber optical communication. We are part of the Fiber Optic Communications Research Center (FORCE) at Chalmers. Research in optoelectronics, with an emphasis on semiconductor lasers, started at Chalmers in the early 1980’s. Today we master everything from laser design and fabrication to laser characterization and system evaluation. We are among the leaders in the development of vertical-cavity surface-emitting lasers (VCSELs), which is a key component for optical interconnects: the short-reach optical links and networks used in datacenters and supercomputers. We participate in European projects and work closely with academic and industrial partners world-wide. To further strengthen our efforts, we will expand our team with a postdoc to work on VCSELs and silicon photonics integration for wavelength-division-multiplexed (WDM) optical interconnects.

WDM enables improvements of interconnect capacity beyond the limits of current technologies. For the short-reach VCSEL-based interconnects, this calls for the development of new multi-wavelength VCSEL array technologies and integration schemes for building high-speed and high-efficiency coarse-WDM transmitters. The project deals with the development of such VCSEL technologies and integration schemes using silicon photonic platforms for multiplexing and interfacing. The project is supported by a large grant from the Swedish Research Council.

Major responsibilities
We seek a postdoc to work in a team of senior researchers, other postdocs and PhD students with complementary skills and tasks. The postdoc will actively participate in the research and development of new VCSEL technologies and integration schemes. The work is mainly experimental and involves VCSEL fabrication and evaluation at the device level as well as integration on silicon photonic platforms for WDM optical interconnects. In addition, a limited amount of efforts on laser design and modelling is expected. Your responsibility as postdoc is to lead and conduct research and to assist PhD students under your guidance. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing.

We offer a competitive salary, excellent working conditions, and state-of-the-art infrastructures in a dynamic and international environment at the forefront of research.

Position summary
Full-time temporary employment. The position is limited to a maximum of two years (1+1).

By the starting date, the highly motivated candidate should have a PhD degree in Engineering Physics, Applied Physics, Electrical Engineering, Photonics, or equivalent. Extensive experience from optoelectronic device fabrication in a cleanroom environment and device characterization using advanced measurement equipment is required. Previous work on VCSELs is a clear merit. Solid knowledge in the areas of semiconductors, optoelectronics and photonics, as well as a good command of English, is also required. Chalmers offers Swedish courses.

To qualify for the position of postdoc, you must have a doctoral degree in a relevant field; the degree should generally not be older than three years.

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