Abstract
Before being incident to a nonlinear medium, a short pulse is intensity-modulated with a bit string pattern, and then made incident. When the pulse light corresponding to a bit value '' is incident to the nonlinear medium, the pulse light is intensity-modulated so that the spectral width thereof is not spread to a predetermined spectral region due to the nonlinear phenomena, thereby producing a light state of being not output from an optical demultiplexer. Meanwhile, when the pulse light corresponding to a bit value '' is incident to the nonlinear medium, the pulse light is intensity-modulated so that the spectral width thereof is spread to the predetermined spectral region due to the nonlinear phenomena, thereby producing a light state of being output from the optical demultiplexer.
