χ(3) nonlinear susceptibility in II-VI compounds and applications for squeezed light generation in semiconductors
We have measured the nonlinear refractive index near half-bandgap (Eg/2) in ZnS and ZnSe by self-phase modulation experiments. The ratio of the nonlinear phase shift and the total optical absorption losses is critically dependent on the detuning from Eg/2. Efficient quadrature squeezing was obtained...
