Volume holographic optical disc (VHOD) technology is simpler than the angular multiplexing holographic system. However, disc rotation usually causes pixel migration, thus reducing signal quality. This study proposes a special geometrical arrangement to counteract pixel migration. Using paraxial approximation analysis, an optimal geometrical distance ratio,(More)
The hybrid wavelength-division multiplexing and optical code-division multiple-access scheme for EPON (called WDM/OCDMA-EPON) is presented over fiber-to-the-home (FTTH) network. In this study, each ONU (optical network unit) group is assigned the maximal-length sequence (M-sequence) code which is popularly used for spectral amplitude coding in OCDMA(More)
