Nonlinear refraction at gain saturation in quantum wells

, 2002
Peculiarities of nonlinear refraction in the active layer of quantum-well heterolasers are established. Effects of spectral broadening are taken into account, the nonlinear refraction spectrum is calculated, and the nonlinear refraction coefficient is ...

Dispersion of extremely nondegenerate nonlinear refraction in semiconductors

, 2017
Dispersion of nondegenerate nonlinear refraction in semiconductors is measured using the Beam-Deflection technique. With large nondegeneracy, n2 is greatly enhanced and exhibits a strong nonlinear dispersion, which rapidly switches sign to negative near ...
