Abstract
We propose an optical code division multiple-access (OCDMA) system that use s in-fiber chirped moire gratings (CMG's) for encoding and decoding of broa dband pulses. In reflection the wavelength-selective and dispersive nature of CMG's can be used to implement wavelength-encoding/temporal-spreading OC DMA. We give examples of codes designed around the constraints imposed by t he encoding devices and present numerical simulations that demonstrate the proposed concept.
