A novel interferometric parallel spectral detection method for optical signals with finite time duration is proposed and experimentally demonstrated. Unlike the conventional schemes that detect temporal signals in the time domain, the proposed method recognizes the frequency spectral components of an optical signal in parallel by observing the spatial interference pattern formed between the optical signal and a multifrequency local light. The operating principle is experimentally confirmed by use of 4-bit-long 200-Mbit/s optical cells.
