摘要
A new mechanism of optical nonlinearity of intrinsic semiconductors is proposed, which is based on bandgap modulation due to the four-wave mixing of interacting waves on the semiconductor surface. This phenomenon is theoretically considered within a one-dimensional model. The corresponding resonances are experimentally found in Ge and Si samples.
