We demonstrated a novel approach for the interrogation of wavelength-modulated optical sensors. The interrogator is based on a tunable on-chip microring filter. By tuning the center wavelength of the microring filter, the center wavelength of the sensor can be readout by the corresponding tuning power. This approach has the potential of constructing a compact and cost-effective interrogator with good performance.
