Abstract: In the present invention, a nonionic surfactant is noticed for a function of dispersing a carbon nanotube, and it is found that a mixture solution of an amide-based organic solvent and a polyvinylpyrrolidone (PVP) or of the amide-based organic solvent, the nonionic surfactant, and the polyvinylpyrrolidone (PVP) has an excellent function as a dispersant for the carbon nanotube. Ultrasonication is required for dispersing a carbon nanotube in the dispersant. The ultrasonication maybe carried out in the step of dispersing the carbon nanotube in the nonionic surfactant and/or the amide-based polar organic solvent, and then the polyvinylpyrrolidone (PVP) may be mixed with the resultant dispersion. Alternatively, a mixture solution of the nonionic surfactant and/or the amide-based polar organic solvent, and the polyvinylpyrrolidone (PVP) is prepared, and then the ultrasonication may be carried out in the step of dispersing the carbon nanotube therein.

Abstract: Non-linear optical characteristics of a carbon nanotube are applied to an optical communication field. An optical transmission medium (12) obtained by incorporating a carbon nanotube having optically non-linear characteristics into a non-linear light transmitting medium is assembled between typical optical transmission medium (14a, 14b) and is used by being combined with an optical circulator (16), whereby the resultant product is used as an optical fuse (breaker) that transmits a normal signal light A but blocks the transmission of an abnormal-intensity light inadvertently produced.
