英文摘要
In semiconducting carbon nanotubes, optical properties are dominated by large oscillator strength and large binding energy of one-dimensional excitons and, therefore, large third-order optical nonlinearity is expected to be observed. In this study, we have measured coherent nonlinear optical spectra by femtosecond transient absorption spectroscopy. We have found a new kind of coherent nonlinear optical responses originating from exciton-exciton scattering as well as optical Stark effects generally observed in low-dimensional semiconductors under a near-resonant excitation condition.
