Surface-enhanced nonlinear four-wave mixing.

We report on a particularly strong third-order nonlinear response from nanostructured gold surfaces. Two incident laser beams with frequencies omega{1} and omega{2} give rise to four-wave mixing (4WM) fields with frequencies 2omega{1}-omega{2} and 2omega{2}-omega{1}. We demonstrate that the nonlinear response can be purely evanescent and that nanostructured surfaces convert the evanescent energ...

Nondegenerate four-wave mixing in rubidium vapor: The diamond configuration

We investigate experimentally and theoretically nondegenerate four-wave mixing in rubidium vapor using a diamond configuration 5S1/2, 5P1/2, 5P3/2, and 6S1/2 levels . We model this process of three classical fields interacting with a four-level atomic system with the Schrödinger equation. The experimental results are in good agreement with theoretical predictions for the generated light as a fu...

Enhanced four-wave mixing efficiency in four-subband semiconductor quantum wells via Fano-type interference.

We propose and analyze an efficient way to enhance four-wave mixing (FWM) signals in a four-subband semiconductor quantum well via Fano-type interference. By using Schrödinger-Maxwell formalism, we derive explicitly analytical expressions for the input probe pulse and the generated FWM field in linear regime under the steady-state condition. With the aid of interference between two excited subb...
