Spectral phase conjugation via extended phase matching
نویسنده
چکیده
It is shown that the copropagating three-wave-mixing parametric process, with appropriate type-II extended phase matching and pumped with a short second-harmonic pulse, can perform spectral phase conjugation and parametric amplification, which shows a threshold behavior analogous to backward-wave oscillation. The process is also analyzed in the Heisenberg picture, which predicts a spontaneous parametric downconversion rate in agreement with the experimental result reported by Kuzucu et al. [Phys. Rev. Lett. 94, 083601 (2005)]. Applications in optical communications, signal processing, and quantum information processing can be envisaged. © 2006 Optical Society of America OCIS codes: 190.3100, 190.4410, 190.4970, 190.5040, 270.4180.

Spectral phase conjugation by quasi-phase-matched three-wave mixing
A novel spectral phase conjugation scheme by three-wave mixing is proposed. It is shown that a phase-conjugated and time-reversed replica of the incoming signal can be generated, if appropriate quasi-phase matching is achieved and the three-wave mixing process is transversely pumped by a short second-harmonic pulse. 2004 Elsevier B.V.

متن کاملSpectral phase conjugation with cross-phase modulation compensation.
Spectral phase conjugation with short pump pulses in a third-order nonlinear material is analyzed in depth. It is shown that if signal amplification is considered, the conversion efficiency can be significantly higher than previously considered, while the spectral phase conjugation operation remains accurate. A novel method of compensating for cross-phase modulation, the main parasitic effect, ...
متن کاملSpontaneous spectral phase conjugation for coincident frequency entanglement
Spontaneous parametric processes pumped transversely with short pulses are studied under a unified framework, which proves that such processes can efficiently generate entangled photon pairs with time anticorrelation and frequency correlation. Improvements upon previously proposed schemes can be made by the use of quasi-phase-matching, four-wave mixing, and cross-phase-modulation compensation. ...
متن کاملDispersion and nonlinearity compensation by spectral phase conjugation.
We propose the use of spectral phase conjugation to compensate for dispersion of all orders, self-phase modulation, and self-steepening of an optical pulse in a fiber. Although this method cannot compensate for loss and intrapulse Raman scattering, it is superior to the previously suggested midway temporal phase conjugation method if high-order dispersion is a main source of distortion. The res...
متن کاملTwo-photon coincident-frequency entanglement via extended phase matching.
We demonstrate a new class of frequency-entangled states generated via spontaneous parametric down-conversion under extended phase-matching conditions. Biphoton entanglement with coincident signal and idler frequencies is observed over a broad bandwidth in periodically poled KTiOPO4. We demonstrate high visibility in Hong-Ou-Mandel interferometric measurements under pulsed pumping without spect...
