ABSTRACT We demonstrate continuous-wave wavelength conversion through four-wave mixing in an endlessly single mode photonic crystal fiber. Phasematching is possible at vanishing pump power in the anomalous dispersion regime between the two zero-dispersion wavelengths. By mixing appropriate pump and idler sources, signals in the range 500-650 nm are obtained in good accordance with calculated phasematching curves. The conversion efficiency from idler to signal power is currently limited to 0.3% by the low spectral density of the pump and idler sources at hand, but can be greatly enhanced by applying narrow line width lasers.

    ABSTRACT: In this paper, a model describing the four-wave mixing (FWM) among an arbitrary amount of incident waves is derived and the predictor-corrector method is exploited to solve the equations. Based on the numerical model, we studied methods to promote the energy exchange among the incident waves. The results show that a proper value of phase mismatch can accelerate the energy exchanging among the pump waves and simultaneously reduces the idler wave powers. This model is applied to investigate the behavior of a multiwavelength erbium-doped fiber laser (MWEDFL) exploiting FWM. According to the simulation, through using a 50-m-long nonlinear fiber with nonlinear coefficient of 11 /W/km, 19 lines can be obtained in the output spectrum with power difference

    ABSTRACT: Photonic crystal fibers (PCFs) have had a substantial impact on nonlinear fiber optics and shortpulsed fiber laser systems due to their novel dispersion properties. The large normal or anomalous waveguide dispersion available in such fibers opens up a number of new opportunities not accessible with standard fiber technology. In this contribution, the fundamentals of PCF dispersion are briefly reviewed along with earlier results. In addition, some of our recent work on dispersion tailoring to facilitate nonlinear processes, and dispersion control in lasers will be presented.

    ABSTRACT: Wavelength conversion based on degenerate four-wave mixing in a photonic crystal fiber with two zero-dispersion wavelengths is investigated both theoretically and experimentally. The proposed concept of universal band translation in a single-pass traveling-wave structure offers a wavelength band rather than a single-wavelength mapping between distant spectral ranges. Near-infrared signals are modulated using both harmonic and pseudorandom bit sequences and translated to the visible optical band. Multiple-channel translation, which produces wavelength-division-multiplexed idlers in the visible band, is demonstrated for the first time. The performance of the translation process is measured both spectrally and temporally for both single- and multiple-channel signals
