Patent ID: 8319963

Claim:
A compact sensor system comprising: an analysis cell configured for photon-matter interaction, where photons are received from a light source; and an integrated-optical spectral analyzer configured for identifying a set of frequencies, said integrated-optical spectral analyzer comprising: a waveguide coupled with said analysis cell, said waveguide comprising a first end and a second end and one or more ring resonator integration sites therebetween, wherein a first end of said waveguide is coupled with said analysis cell, said waveguide configured for propagating said set of frequencies through said waveguide from said analysis cell to said second end; one or more ring resonators coupled with said one or more ring resonator integration sites of said waveguide, said one or more ring resonators comprising a predetermined bandwidth and configured for capturing said set of frequencies corresponding to frequencies within said predetermined bandwidth; and one or more frequency detectors coupled with said one or more tunable ring resonators, said one or more frequency detectors configured for generating electrical signals that identify each of said set of frequencies.
