Abstract: A fluid sensor that includes fluid sensitive interferometric nanostructure layers configured into an open-air resonant structure. Another fluid sensor also includes a polarization sensitive photodetector configured to detect optical contributions of different components of a fluid to the structure. A photonic sensor system includes: a photodetector; a signal processor coupled to the photodetector; and a sensor structure configured to provide fluid-response selectivity, spatially distribute light, and to receive light from a light source and convey light to the photodetector. A method of selective measurement of components in fluid in a process area includes: exposing a sensing structure to the fluid; interrogating the sensing structure with light from outside the process area; measuring a change in optical properties of the sensing structure; correlating the measured change to a stored value; and providing quantitative values of levels of the components in the fluid.
