An on-chip interrogator for wavelength-modulated optical sensors is developed based on a thermal tunable silicon microring resonator. The center wavelength of the sensors can be readout from the tuning power corresponding to the peak optical output intensity of the system by scanning the resonant wavelength of the microring filter. Both on-chip (microring) and off-chip (FBG) wavelength-modulated sensor are interrogated by our microring interrogator.
