Abstract

Optical resonances of spherical microresonators are of great interest measurements with high sensitivity. Usually the quantity to be measured is determined by the shift of the resonances of a single particle. Unfortunately, for this purpose, an expensive low-bandwidth tunable laser system with high accuracy is needed. When using an array of microresonators with slightly different size, each particle has a different resonance behavior. A change of the quantity to be measured leads to a change of the intensity distribution over the entire array. Therefore, using a microresonator array it is sufficient to measure the intensity distribution over all particles at a fixed wavelength.
