  1. Taking Detection to the Limit: Biosensing with Optical Microcavities


We demonstrate the photorefractive tuning of the whispering gallery modes of a single BaTiO3 microsphere resonator integrated inside a grapefruit-shaped microstructured optical fibre, upon CW laser irradiation at 532 nm while using irradiation intensities up to 5.5 W/cm2. Temporal evolution results of the WGM spectra are provided with respect to the illumination and relaxation conditions applied.
