Reconfigurable time domain spectral phase encoding/decoding scheme using fibre Bragg gratings for two-dimensional coherent OCDMA

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.
