Human activities are driving climate change through greenhouse gas (GHG) emissions and worsening air quality, both of which pose serious threats to human health and ecosystems. To address these challenges, stricter environmental regulations are being introduced worldwide, but current air monitoring systems are not well-suited to meet these demands.

The primary goal of the RAVEN project is to design and develop two innovative, complementary, compact, and cost-effective sensors based on photonic integrated circuits (PICs). These sensors will work together to provide continuous gas analysis over a wide wavelength range (600-3000 nm), enabling the detection and measurement of numerous analytes with high sensitivity, accuracy, and precision.
