We propose an optical code division multiple-access (OCDMA) system that uses in-fiber chirped moiré gratings (CMG’s) for encoding and decoding of broadband pulses. In reflection the wavelength-selective and dispersive nature of CMG’s can be used to implement wavelength-encoding/temporal-spreading OCDMA. We give examples of codes designed around the constraints imposed by the encoding devices and present numerical simulations that demonstrate the proposed concept.
