The MILADO project aims to revolutionize mid-infrared (MIR) laser technology by developing cost-effective, high-volume manufacturing processes for Quantum Cascade Lasers (QCLs). These lasers are essential for various spectroscopic applications due to their compactness, high power spectral density, and broad spectral coverage up to 12 µm. However, their high costs limit market penetration. MILADO merges "group III-V" and silicon photonics to create affordable, compact MIR light sources by using established complementary metal-oxide-semiconductor (CMOS) processes. This shift from expensive, complex craft production to scalable manufacturing could reduce QCL prices from thousands to tens of euros. Our innovation will revolutionize applications in bioanalysis, such as oncology, microbiology, and in detecting waste anaesthetic gases. Additionally, MILADO aims replacing traditional assemblies with monolithic integration and serves as a fundamental building block of a general technology platform that also integrate sensors and actuators in micro-electromechanical systems (MEMS) technology. Our standardized approach will decrease costs, increase reproducibility, and benefit applications requiring miniaturized, portable, and robust MIR sensor solutions.
