Project assistant position in III-nitride photonic-crystal surface-emitting lasers
Chalmers University of TechnologyPublicerad: 2026-05-15
Ansök senast: Öppet tillsvidare
Beskrivning
Are you interested in cutting-edge photonics research and hands-on work with advanced optoelectronic devices? Join a leading research group at Chalmers this summer and contribute to the development of next-generation photonic-crystal surface-emitting lasers (PCSELs).
Information about the research group and project
The Photonics Laboratory at the Department of Microtechnology and Nanoscience (MC2), with about 35 researchers, works in optoelectronics, ultrafast optics and fiber-optical communication. A strong research focus is on ultraviolet (UV) and blue surface-emitting devices, such as vertical-cavity surface-emitting lasers (VCSELs), photonic-crystal surface emitting lasers (PCSELs), light-emitting diodes (LEDs), and resonant-cavity LEDs (RCLEDs). Our expertise includes device design and simulation, laser fabrication, and material and device characterization. We have developed a novel thin-film lift-off process for AlGaN-materials based on electrochemical etching, enabling integration of III-nitride thin films with various photonic structures, such as dielectric cavities with improved quality factors. These advances have enabled us to demonstrate the world's first blue VCSEL with a high-contrast grating for polarization pinning, thin-film flip-chip UVB LEDs and optically pumped VCSELs at 310 and 275 nm. More recently, we have also demonstrated the first optically pumped UV-B and UV-C PCSELs. We are now looking to hire a project assistant for the summer of 2026 to support our research activities on PCSELs.
Main responsibilities
You will contribute to the simulation, fabrication, and/or characterization of PCSELs, working with state-of-the-art equipment in our cleanroom and characterization laboratories.
Qualifications
You are currently pursuing a Master's degree and have:
It is meritorious if you have experience with III-nitride materials.
Contract terms
The contract is a full-time temporary employment of up to 3 months, with a preferred start date around mid-June.
What we offer
Chalmers provides a cultivating and inspiring working environment in the coastal city of Gothenburg.
