nanoplus Nanosystems and Technologies GmbH
Nanoplus was founded in 1998 as a spin-off from the department of Technical Physics at Würzburg University to transfer research results into applications and products with a specialization in optoelectronics devices and customer specific micro- and nano-structuring.
The company is equipped with a complete process line for semiconductor laser fabrication, comprising different dry etch systems, sputter systems, evaporators, mask aligners, laser mounting facilities, etc. in a 250 m2 clean room (class 100-10000). Nanoplus facilities also comprise 120 m2 of laboratory space for technical supply (a/c, high purity gases, water preparation) and 500 m2 of office and characterization space.
A key product of nanoplus are distributed feedback (DFB) laser diodes based on a unique and patented technology. DFB lasers realized by this technique have a high single mode yield, high efficiencies as well as high sidemode supression ratio (SMSR) around 40dB combined with low back reflection sensitivity and thresholds. The technology has been optimized for a wide variety of semiconductor heterostructures including GaSb, InP and GaAs based materials. Based on these material systems, nanoplus produces DFB and Fabry-Perot laser diodes in the wavelength range from 0.7 up to 2.8 µm for sensing and spectroscopy as well as telecom applications.
