Optical planar waveguide sensors, able to detect and process information from the environment in a fast, cost-effective, and remote fashion, are of great interest currently in different application areas including security, metrology, automotive, aerospace, consumer. Traditionally, high-performance communication systems were based on rectangular waveguides (RWGs) to guide high-frequency signals. Newer, efficient RWG-like systems are now available with the added value of low cost, low volume and low weight, together with compactness and ease of manufacture. However, the existing DONNs based on free-space diffractive optical elements are bulky and unsteady. FIMMPROP is probably the most widely used propagation tool for the modelling of silicon photonics: rigorous (no slowly varying approximation), fully vectorial, offering wide angle capability and very high design flexibility. Integrated optical waveguide systems have emerged as foundational components for next-generation sensing technologies, owing to their exceptional miniaturization, high integration density, and compatibility with scalable planar fabrication.
