We report a digital biosensor with the logic gate in an optical fiber microcavity. The logic gate is controlled by analyte-induced DNA conformation changes, switching laser emission through the FRET effect. Logic gates of OR and INHIBIT are demonstrated for digital biosensing with a wide threshold range, about one order of magnitude higher than fluorescence.
