Leti has prototyped an optical chemical sensor using mid-infrared silicon photonics that can be integrated in smartphones and other portable devices. Mid-IR chemical sensors operate in the spectral range of 2.5µm to 12µm, and are considered the paradigm of innovative silicon-photonic devices. In less than a decade, chemical sensing has become a key application for ...
