Nondegenerate optical Kerr effect in semiconductors
... Eg must be included. In practice, however, above band-gap resonance excitation leads to well known carrier effects (e.g., band-filling) that mask the bound electronic contributions. Above band-gap ultrafast bound-electronic nonlinearities have, nevertheless, been observed in semiconductor laser ampl ...
