This study presents an olfactory sensor based on silicon photonics technology, capable of analyzing various volatile organic compounds at the ppm level.
Silicon photonics can address a variety of applications, from datacom and biosensing to lidars. Recently, this technology has been explored for gas sensing. Detection and identification of odors remains a critical challenge in diverse areas such as air quality, food spoilage, or personal well-being. In this work, we present an olfactory sensor based on an array of 64 biofunctionalized Mach-Zehnder interferometers integrated on a silicon nitride platform. The ability to analyze odors at ppm level is demonstrated for several volatile organic compounds.(c) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
