Degenerate four waves mixing in multilayer nanoshell
Authors
Abstract:
We will present a detailed investigation of intersubband transitions process in core-multi shells quantum dots. The confined wave functions and eigenenergies of electrons in quantum dots have been calculated under the effective-mass approximation by solving a three-dimensional Schrodinger equation. Excellent dependence is found between size effects, time relaxation and degenerate four wave mixing (DFWM). We found that the enhancement of the thickness layers lead to strongly enhancement in peak value of DFWM.

This work treats degenerate four-wave mixing ~DFWM! in noncentrosymmetric materials, taking into full account the fact that the DFWM signal arises from third-order nonlinear optical effects as well as from two distinct combinations of second-order effects: second-harmonic generation plus difference frequency generation and optical rectification plus Pockels effect. Because of these second order...

Fluorescence microscopy has been widely used to explore the nanoscale world because of its superb sensitivity, but it is limited to fluorescent samples. Hence, various spectroscopic contrasts have been explored for imaging nonfluorescent species. Here we report a multiphoton microscopy based on single-beam near-degenerate four wave mixing (ND-FWM), by detecting a coherent signal generated by th...

In a recent experiment, Campbell et al. Phys. Rev. Lett. 96, 020406 2006 observed degenerate four-wave mixing of matter waves in a one-dimensional optical lattice. We analyze the essential quantum features of the experiment to show that entanglement is created between the quadratures of the two scattered atomic clouds and is a true many-body rather than two-body phenomenon. We demonstrate that ...
