Phase-sensitive amplification via multi-phase-matched four-wave mixing

Phase matched parametric amplification via four-wave mixing in optical microfibers.

Four-wave mixing (FWM) based parametric amplification in optical microfibers (OMFs) is demonstrated over a wavelength range of over 1000 nm by exploiting their tailorable dispersion characteristics to achieve phase matching. Simulations indicate that for any set of wavelengths satisfying the FWM energy conservation condition there are two diameters at which phase matching in the fundamental mod...

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.

Ultrafast temporal pulse shaping via phase-sensitive three-wave mixing.

It is well-known that the process of optical parametric amplification (OPA) can be sensitive to the phases of the incident waves. In OPA realized by three-wave mixing, injection of all three waves into the same mode with appropriate phase relationship results in amplification of the signal phase, with an associated deamplification of the signal energy. Prospects for the use of this technique in...

Cross Phase Modulation and Four - Wave Mixing

Continuous - wave phase - sensitive parametric image amplification

(Received 00 Month 200x; In final form 00 Month 200x) We study experimentally parametric amplification in the continuous regime using a transverse-degenerate type-II Optical Parametric Oscillator operated below threshold. We demonstrate that this device is able to amplify either in the phase insensitive or phase sensitive way first a single mode beam, then a multimode image. Furthermore the tot...
