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.
The Filmetrics F20 benchtop film thickness measurement tool is a general purpose instrument for measuring thickness and refractive index.

AZoOptics speaks to Dr. Keith Paulsen about the importance of breast cancer detection and the introduction of his team's deep-learning algorithm that associates spatial images of tissue optical properties with optical signal patterns measured during an imaging experiment or patient exam.
Prof. Simon Scheuring & Dr. Alma P. Perrino
AZoOptics speaks to Prof. Simon Scheuring & Dr. Alma P. Perrino about their recent research using a new line-scanning high-speed atomic force microscopy technique. The method helps characterize the single-molecule kinetics of wild-type bR (bR-WT) exposed to continuous light and short light pulses.
