This paper presents first sensing results for an optical fiber probe sensor based on silicon-on-insulator ring resonators. The proposed device combines the high quality of silicon-on-insulator ring resonator biosensors with the portability of optical fibers. The ring resonator is transferred from a silicon-on-insulator (SOI) chip to the tip of an optical fiber maintaining the sensor performance of the ring measured on a SOI sample.
