Abstract
An optical device is useful for analyzing an optical signal pulse to determine information related to the pulse, such as information related to its temporal coherence length. The optical device generally includes a plurality of interferometric devices to generate one or more respective interference patterns from the optical signal pulse, and a plurality of detectors associated with each respective interferometric device to receive the one or more respective interference patterns. At least one of the plurality of interferometric devices is disposed in a glass substrate. The optical device may be integrated in an optical correlation system having an analyzer coupled to the plurality of detectors to determine the temporal coherence length or other pulse-related information for the optical signal pulse based on the received interference patterns.
