Spectral Amplitude Coding Optical CDMA Networks Using $2^{m}\times 2^{m}$ Waveguide Gratings

One new code family for spectral amplitude coding optical code-division multiple-access is proposed. Due to the cyclic property of the proposed code, one arrayed waveguide grating (AWG) can be used to generate all the codewords in one code. Since can be an even number such as eight, commercial AWGs can be used for coder implementation.
