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...
Asynchronous OCDMA systems are demonstrated using 511 chip, 640 Gchip/s and 31 chip, 40 Gchip/s with different types of fiber Bragg grating encoders/decoders. Error-free transmission has been achieved with up to five OCDMA users.
