There is growing demand for robust, reliable, low cost, and easy to use sensor systems that feature multiparameter analysis in many application areas ranging from safety and security to point of care and medical diagnostics. Here, we highlight the theory and show first experimental results on a novel approach targeting the realization of massively multiplexed sensor arrays. The presented sensor platform is based on arrays of frequency-modulated integrated optical microring resonators (MRR) fed by a single bus waveguide combined with lock-in detection to filter out in a reliable and simple manner their individual response to external stimuli. The working principle is exemplified on an array of four thermo-optically modulated MRR. It is shown that with this technique tracking of individual resonances is possible even in case of strong spectral overlap.
