A novel fiber Bragg grating (FBG) decoder is proposed for simultaneous time domain coherent optical code recognition and chromatic dispersion compensation. We derive the target frequency response of such a device and use the discrete layer peeling method to synthesize it. This dispersion compensation FBG decoder guarantees the system performance and simplifies the network structure. We also discuss...
We demonstrate the reconfigurable time domain spectral phase encoding/decoding (SPED) schemes using fibre Bragg gratings (FBG) for the first time. Chirped FBG is used for coherent spectral phase encoded OCDMA. FBG array with two-dimensional optical code patterns is used for two-dimensional coherent OCDMA.
