Twenty-One Semiconductors

Twenty-One Semiconductors GmbH was founded in 2019 as a spin-off of the Institute of Semiconductor Optics and Functional Interfaces (IHFG) at the University of Stuttgart. The company produces and markets a completely new type of laser crystals that can be used to efficiently generate laser radiation in the visible spectral range.
The underlying MEXL technology enables laser manufacturers to realize a new generation of laser sources for biomedical applications to obtain more detailed information when analysing cell and tissue samples.

Novel laser technology for biomedicine - Twenty-One Semiconductors successfully closes seed financing round with High-Tech Gründerfonds.

High-Tech Gründerfonds (HTGF) invests in the start-up Twenty-One Semiconductors (21S) as part of a first round of financing. The spin-off from the University of Stuttgart produces semiconductor-based laser crystals for biomedical applications. These crystals enable the realization of laser modules in the yellow spectral range, which is difficult to access with traditional laser technologies. Such yellow lasers are used to significantly increase the information content of biomedical investig
