Quadratic electro-optic effects in semiconductor carbon nanotubes

We investigate the third-order nonlinear optical susceptibility χ (3)( ω) responsible for the quadratic electro-optic effects (electro-absorption and the DC Kerr effect) in single-shell semiconductor carbon nanotubes. Distinct new features in the dispersion behaviour of χ (3)( ω) (e.g. change of sig...

Description
Summary:We investigate the third-order nonlinear optical susceptibility χ (3)( ω) responsible for the quadratic electro-optic effects (electro-absorption and the DC Kerr effect) in single-shell semiconductor carbon nanotubes. Distinct new features in the dispersion behaviour of χ (3)( ω) (e.g. change of sign) are found, which are of fundamental importance to the electro-optic device potential of nanotubes.
