Travelling-wave resonant four-wave mixing breaks the limits of cavity-enhanced all-optical wavelength conversion
Wave mixing inside optical resonators, while experiencing a large enhancement of the nonlinear interaction efficiency, suffers from strong bandwidth constraints, preventing its practical exploitation for processing broad-band signals. Here we show that such limits are overcome by the new concept of travelling-wave resonant four-wave mixing (FWM). This approach combines the efficiency enhancemen...
متن کاملAll-Optical Switching of Picosecond Pulses by Four-Wave Mixing in a Semiconductor Optical Amplifier
High-speed all-optical switching is demonstrated by four-wave mixing (FWM) of picosecond pulses using semiconductor optical amplifiers (SOA). A light source for measurement and switching in the 1.5 μm region is produced using a normal group velocity dispersion fiber and optical parametric oscillator. The output supercontinuum (SC) optical pulses, with a spectral width of approximately 300 nm, a...

متن کاملAll-optical Wavelength Conversion Based on Four-wave Mixing in Silicon Waveguides
All-optical wavelength conversion is investigated using fourwave mixing in silicon waveguides. The influences of nonlinear losses caused by two-photon absorption (TPA) and TPA-induced free-carrier absorption on the conversion efficiency and phase-matching condition are analyzed. The conversion bandwidth is tempted to enhance by optimizing the waveguide geometry and using the two-pump regime. An...
متن کاملAll-optical logic circuits based on polarization properties of nondegenerate four-wave mixing
All-optical logic circuits based on the polarization properties of nondegenerate four-wave mixing are proposed. Schemes to perform multiple triple-product logic functions are discussed, and it is shown that higher-level Boolean operations that involve several bits can be implemented without resorting to the standard two-input gates. As a simple illustration of the idea, a circuit that performs ...
