Cascaded four-wave mixing was theoretically and experimentally studied in transparent bulk media. The obtained sidebands show small angle dispersion, but have good beam quality with M2 factor better than 1.1 in the measurement. The center wavelength of the generated multicolor sideband can be ...
We report on the broadband-cascaded four-wave mixing (CFWM) products generated in a photonic crystal fiber pumped by a picosecond pulse and seeded by two continuous wave (CW) signals. The equal and unequal frequency spaced CFWM products could be obtained through continuously tuning one of the CW...
We present a theoretical model and respective numerical simulation of cascaded four-wave mixing of femtosecond pulses in bulk chi(3) media, evidencing the importance of two-dimensional interaction geometries in the efficient generation of frequency-converted beams, and in agreement with the experimental...

One-to-nine multicasting of a 10.7-Gb/s RZ-DPSK signal is demonstrated on the basis of cascaded four-wave mixing (FWM) in a and fluorine-doped highly nonlinear fiber. This structure could significantly improve the FWM efficiencies of most channels with the required pump power of only . There...
The Kerr nonlinearity effects for multi-frequency radiation can be treated in the frequency domain as cascaded four-wave mixing (FWM) between corresponding modes/frequencies8, 9 which results in generation of additional spectral components, thus forming a coherent comb. Kerr frequency combs can be ...
13and spontaneous parametric processes14,15,16,17,18,19,20,21,22, are developed to generate correlated/entangled photon-pairs. The latter one includes spontaneous parametric down conversion (SPDC) and spontaneous four-wave mixing (SFWM), already widely utilized in several applications23,24,25,26...
The Third Order Nonlinear Process in Femtosecond Time-Resolved Four-Wave Mixing and Femtosecond Lasers Some basic properties of higher order nonlinear optical processes are examined in this thesis. Two novel applications of third order nonlinear optical processes to device physics are also discussed here...
The electrode structure of the present invention is use in overlap cascaded structure packages of different color LED chips, by mixing two or three color light to have a different color light or white light. FIG.6 shows the electrode structure of a bottom LED die for overlap cascaded packaging...
Here we show that it is possible to cascade OR and NOT gates to realize a plasmonic inverse NOR gate in a four-terminal branched silver nanowire network. We use quantum dot (QD) near-field imaging to trace the plasmon wave packets through the branched network and to demonstrate precise ...
