摘要:

The dispersion of a parameter quantifying the effects of two‐photon absorption on all‐optical waveguide switching devices is evaluated for the case of semiconductors in a two band model. Serious limitations are predicted based on the nonresonant bound electron response for photon energies between the band gap and one half the band gap.
