Guided by environmental policies, the automobile industry is concerned to reduce the carbon footprint of vehicles. Automotive suppliers develop innovative combustion engines to control CO2 and NOx concentration in exhaust fumes.
[ 115 ]NOx is produced during fuel combustion at power plants and other industrial facilities. When it reacts with SO2 it causes acid rain. For this reason NOx and SO2 emissions are restricted and need to be monitored.
[ 67 ]nanoplus distributed feedback lasers show outstanding spectral, tuning and electrical properties.

nanoplus uses a unique and patented technology for DFB laser manufacturing. We apply a lateral metal grating along the ridge waveguide, which is independent of the material system. Read more about our patented distributed feedback technology.
