Abstract
- Spectral and nonlinear optical properties of InAs nanowires synthesized via molecular beam epitaxy suspended in isopropanol are studied in this work at room temperature. The absorption spectra with a characteristic maximum at a wavelength of 235 nm, as well as the Raman spectra in a range of 180–280 cm–1, are obtained. The nonlinear transmittance of InAs nanowires with diameters less than the exciton Bohr radius was firstly investigated by a two-photon excitation in the transparent region (λ = 468 nm). The effect of cumulative bleaching, the manifestation of which is associated with the dynamic Stark effect, was discovered.
