  "abstract": "Airborne fungal pathogens, such as Penicillium expansum, pose a severe threat to post-harvest crop preservation and food safety, demanding rapid and reliable detection methods. This study presents a photonic integrated sensing platform, based on Ge-Se-Te RIB optical waveguides, as a proof-of-concept for the discrimination of fungal spores under controlled laboratory conditions in the short-wave infrared (SWIR) range. To evaluate the performance of the sensor over a comprehensive 45-day experimental campaign, Finite Element Method (FEM) simulations were combined with advanced chemometric analysis. FEM modeling confirmed the evanescent field interaction with micrometer-sized spores on the waveguide surface. To extract the subtle biological signal resulting from high-density spore deposition from dominant system drifts and environmental noise, ANOVA-Simultaneous Component Analysis (ASCA) was applied to the multidimensional spectral data. ASCA successfully isolated the specific variance related to spore deposition, even though it accounted for only 0.2% of the global variance. These results highlight the potential of combining chalcogenide waveguide technologies with ASCA-driven analytics for scattering-based, label-free bio-sensing applications, paving the way toward future quantitative and species-selective developments in the mid-wave infrared (MWIR).",
