Abstract
Methods and apparatus are provided for the recognition of an optical signal that is encoded with a specified temporal pattern. Nonlinear optical interactions and time-integrating optical detectors are used to identify temporally short correlation peaks in an optical signal in an optical communication system without temporally resolving the correlation signal. The apparatus includes means for decoding an encoded optical waveform, a time-integrating nonlinear detection system, a time-integrating linear detection system for proper normalization, and thresholding electronics that produce voltage pulses corresponding to the presence of specified waveforms at the detector input.
