Third Order Nonlinear Susceptibility

We describe experiments to generate non-classical quadrature squeezed states of light by four-wave mixing in semiconductors. Squeezing can be achieved with either the diagonal or off-diagonal components of the third-order nonlinear susceptibility tensor. We have demonstrated squeezing by self-phase modulation in ZnS at 780 nm, and by cross-phase modulation in ZnSe at 960 nm. Possibilities for generating squeezed light in other materials by these techniques are discussed.

Third Order Nonlinear Susceptibility

A novel method for determination of real and imaginary parts of a third-order nonlinear susceptibility tensor in a single measurement is proposed and demonstrated. The method measures directly the ratio of imaginary to real part of the [Formula: see text] coefficient in isotropic media. Its sensitivity is high enough to enable measurements with unamplified pulses from a mode-locked Ti:Sapphire laser. Results of measurements for CS 2, 1-Chlornaphtalene and polycrystalline ZnSe are presented.

Third Order Nonlinear Susceptibility

An analytical expression of the third order nonlinear susceptibility χ(3) has been derived rigorously for a system of interacting Frenkel excitons in a one-dimensional chain of size N with the periodic boundary conditions. It has been clarified that the magnitude of interacting potential between excitons strongly influences the size dependence of χ(3) in the long wavelength approximation, which is well explained in terms of the cancellation effect between the contributions from [ground state] - [one-exciton] transitions and those from [one-exciton] - [two-exciton state] transitions.
