Abstract:
1. An optical transmission apparatus comprising: a light source outputting either pulse light or continuous light; an intensity modulator having the light output from the light source incident thereto, and performing intensity modulation to thereby output pulse light intensity-modulated according to a predetermined bit string pattern of data; a nonlinear medium having the pulse light output from the intensity modulator incident thereto, bringing about nonlinear phenomena upon the pulse light output from the intensity modulator and incident to the nonlinear medium, and thereby spreading spectral width of intensity-modulated pulse light having peak intensity of a predetermined level or higher to a predetermined spectral region, and thereby outputting a spectral width spread pulse light; and an optical wavelength demultiplexer having the spectral width spread pulse light output from the nonlinear medium incident thereto, and demultiplexing incident spectral width spread pulse light having a wavelength component in the predetermined spectral region into a plurality of wavelengths, wherein
