Ghost imaging with different frequencies through non-degenerated four-wave mixing

Polarization Independent Wavelength Conversion Using Fiber Four-Wave Mixing with Two Orthogonal Pump Lights of Different Frequencies

This paper describes polarization independent wavelength conversion, utilizing fiber four-wave mixing. By using two orthogonal pump lights having different frequencies, the baseband signal of the wavelength converted light is insensitive to the polarization state of the original signal light. Experiments that include bit error measurements confirm the polarization independent operation.

Imaging Gold Nanorods by Plasmon-Resonance-Enhanced Four Wave Mixing

Forward four-wave mixing with defocusing nonlinearity.

We experimentally demonstrate degenerate, forward four-wave mixing effects in a self-defocusing photorefractive medium, in both one and two transverse dimensions. We observe the nonlinear evolution of new modes as a function of propagation distance, in both the near-field and far-field (Fourier space) regions.

One-way coherent imaging through a distorting medium using four-wave mixing.

A proposal and an analysis are presented for imaging through a distorting medium using field multiplication by four-wave mixing.

Fundamentals of Highly Non-Degenerate Cascaded Four-Wave Mixing

By crossing two intense ultrashort laser pulses with different colors in a transparent medium, like a simple piece of glass, a fan of multicolored broadband light pulses can be simultaneously generated. These newly generated pulses are emitted in several well-defined directions and can cover a broad spectral range, from the infrared to the ultraviolet and beyond. This beautiful phenomenon, firs...
