Home/Labs/Lund

Myfab Lund or Lund Nano Lab (LNL) is a cleanroom facility with a world-class expertise in epitaxial growth and processing of semiconductor nanowires. The laboratory is one of the essential resources for NanoLund researchers, but it is open for other academic and industrial users. The Myfab Lund staff supports its customers with the cleanroom and safety training, equipment support and technology development. The laboratory is actively used in several courses for undergraduate and graduate students thus linking education with fundamental/applied research and industry.

We welcome all users to access the equipment for fundamental research and development in the fields of materials science, nanotechnology, microelectronics, life science and quantum technology. Myfab Lund is staffed with metrology, equipment and process experts who are available to train and guide you. We also educate students enrolled at Lund University and participate in outreach activities for the local community and society. Myfab Lund has been a member of Myfab, the Swedish Research Infrastructure for Micro and Nano Fabrication since 2016.

Researchers at Chalmers University of Technology have for the first time succeeded in combining two major research fields in photonics by creating a nanoobject with unique optical qualities. Since the object is a thousand times thinner than the human hair, yet very powerful, the breakthrough has great potential in the development of efficient and compact nonlinear optical devices.
“My feeling is that this discovery has a great potential,” says Professor Timur Shegai, who led the study at Chalmers.

Photonic applications harness the power of light-matter interactions to generate various intriguing phenomena. This has enabled major advances in communications, medicine, and spectroscopy, among others, and is also used in laser and quantum technologies. Now, researchers at the Department of Physics at Chalmers University of Technology have succeeded in combining two major research fields – nonlinear and high-index nanophotonics – in a single disk-like nanoobject.

“We were amazed and happy by what we managed to achieve. The disk looking structure is much smaller than the wavelength of light, yet it's a very efficient light frequency converter. It is also 10,000 times, or maybe even higher, more efficient than the unstructured material of the same kind, proving that nano structuring is the way to boost efficiency,” says doctor Georgii Zograf, lead author of the article in Nature Photonics where the research results are presented.
