Claim:
1. An optical sensing system, the optical sensing system comprising: a light separation element configured to separate an input light into a plurality of sliced lights, each sliced light of the plurality of sliced lights having a different range of wavelengths; a plurality of first resonators, each first resonator of the plurality of first resonators configured to receive one respective sliced light of the plurality of sliced lights, wherein an effective refractive index of each first resonator is changeable in response to a change in a refractive index of a cladding of the respective first resonator; and wherein at least one first resonator of the plurality of first resonators is configured to contact a sample so that a refractive index of a cladding of the at least one first resonator is changed as a result of the at least one first resonator brought into contact with the sample; at least one second resonator coupled to the plurality of first resonators; a plurality of detectors, wherein one respective detector of the plurality of detectors is configured to measure a respective intensity of the respective sliced light based on a difference between a resonant wavelength of each first resonator and a resonant wavelength of the at least one second resonator; wherein the difference between the resonant wavelength of each first resonator and the resonant wavelength of the at least one second resonator is based on the effective refractive index of each first resonator.
