Abstract

The Al2O3 waveguide technology was explored for sensing applications. Passive microring resonators with a quality factor in air of 3.2×105 were developed with a bulk refractive index sensitivity of ~100 nm/RIU and limit of detection of ~10-6 RIU. These were functionalized to detect the biomarker rhS100A4 from urine down to concentrations of 3 nM. Furthermore, Al2O3:Yb3+ microdisk lasers were realized that exhibited single mode lasing operation in water. Their lasing wavelength was tuned by varying the bulk refractive index and a bulk refractive index sensitivity of ~20 nm/RIU with a LOD of ~3×10-6 was achieved.
