Post-Doc Position In III-Nitride-Based Vertical-Cavity Surface-Emitting Lasers


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 academia, 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 group and the project

The Photonics Laboratory at the Department of Microtechnology and Nanoscience conducts research in optoelectronics and fibre optics. Within optoelectronics we have a strong focus on vertical-cavity surface-emitting lasers (VCSELs) for emission in the infrared (GaAs-based) as well as for emission in the ultraviolet to blue (III-nitride-based). Besides VCSELs our wide bandgap optoelectronics team also focuses on thin-film flip-chip light-emitting diodes emitting in the ultraviolet. A device concept enabled by electrochemical etching of AlGaN. To further strengthen our efforts we will now expand our team with a post-doc working on blue-emitting VCSELs.

Major responsibilities

Your major responsibility will be to develop electrically injected VCSELs from III-nitride materials emitting in the blue wavelength regime. Your work will be mainly experimental and will focus on device fabrication using state-of-the-art equipment in our clean room as well as characterization of fabricated devices in our measurement laboratory. In addition, you will have access to our in-house-developed VCSEL simulation tools for laser design and modelling. Part of the work will be conducted in close collaboration with external partners.

Position summary

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


By the starting date, you should have a PhD degree, with knowledge in III-nitride device fabrication and characterization. The degree should generally not be older than three years. Experience from device simulations or epitaxial growth of III-nitrides will be a merit. Important personal qualities are enthusiasm, ability to drive and conclude projects independently, creativity and problem-solving ability. Good cooperation and social abilities are also important.

Excellent communication skills in spoken and written English are necessary. Chalmers offers Swedish courses.

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