Performance Evaluation of Passive and Active Optical Pattern Recognition Structures: A Comparison Study

This paper experimentally demonstrates the performance of passive and active optical pattern recognition structures. The passive structures included in this study are based on Fiber Bragg Gratings (FBG), and Arrayed Waveguide gratings (A WG), whereas the active structure employs reconfigurable Opto-VLSI processors to recognise different bit patterns. All structures are demonstrated at IOGbps and the performance of Opto-VLSI-based pattern recognition structures are compared to the perfonnances of their passive counterparts in terms of reconfigurability and optical losses.
