All-optical logic circuits based on polarization properties of nondegenerate four-wave mixing
نویسندگان
چکیده
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 error correction on a (3,1) Hamming code is demonstrated. Error-free performance (bit error rate of ,1029) at 2.5 Gbit/s is achieved after single-error correction on the Hamming word with 50% errors. © 2001 Optical Society of America OCIS codes: 200.3760, 190.4380.

Suppression of Four Wave Mixing Based on the Pairing Combinations of Differently Linear-Polarized Optical Signals in WDM System
Data transmission in optical systems and increased transmission distance capacity benefit by using optical amplification wavelength division multiplexing (WDM) technology. The combination of four waves (FWM) is a non-linear effect in the wavelength division multiplex (WDM), when more than two wavelengths of light in a fiber launch will occur. FWM amount depends on the channel, the channel spaci...
متن کاملPolarization-Dependent Optical Nonlinearities of Multiquantum-Well Laser Amplifiers Studied by Four-Wave Mixing
We present a detailed study of the polarization properties of four-wave mixing in multiquantum-well (MQW) semiconductor optical amplifiers (SOA’s). In particular, the polarization selection rules relevant to all processes contributing to the generation of the four-wave mixing signal are rigorously derived and discussed. We then show the importance of these results in applications where four-wav...

متن کاملUltrafast WDM Logic - Selected Topics in Quantum Electronics, IEEE Journal on
Ultrafast all-optical logic gates that accept optical inputs in which wavelength designates bit position within the overall byte are proposed and demonstrated. Four-wave mixing is shown to provide a conditional test function that can be used to construct any multi-input logic gate. Polarization provides the logic state for each bit. Implementations that use semiconductor optical amplifiers as t...
متن کاملModified two-photon absorption and dispersion of ultrafast third-order polarization beats via twin noisy driving fields
We investigate the color-locked twin-noisy-field correlation effects in third-order nonlinear absorption and dispersion of ultrafast polarization beats. We demonstrate a phase-sensitive method for studying the twophoton nondegenerate four-wave mixing NDFWM due to atomic coherence in a multilevel system. The reference signal is another one-photon degenerate four-wave-mixing signal, which propaga...
