| 摘要 |
<p>An optical CDMA encoder-decoder is constructed by combining arrayed-waveguide gratings, matrix optical switches, and delay lines, otherwise by combining arrayed-waveguide gratings and variable delay lines, thus providing an encoding process that a wavelength change with respect to time in optical pulses. <IMAGE></p> |
