Abstract:
1. An optical pulse correlation system for analyzing an optical signal pulse, comprising: a glass substrate with an interior bulk; an interferometer array of interferometric elements wherein each interferometric element of the interferometer array includes a waveguide that introduces a respective time delay for autocorrelation of the optical signal pulse, each interferometric element being disposed within the interior bulk of the glass substrate; a plurality of detectors in optical communication with the interferometer array to receive one or more interference patterns generated by the interferometer array; and an analyzer coupled to the plurality of detectors to determine temporal coherence length information for the optical signal pulse based on the received interference patterns wherein the temporal coherence length information determined by the analyzer comprises data that brackets the temporal coherence length of the optical signal pulse based on two interferometric elements of the interferometer array having time delays near the temporal coherence length of the optical signal pulse.
