Continuous-wave tunable optical parametric generation in a photonic-crystal fiber

Continuous-Wave Band Translation Between the Near-Infrared and Visible Spectral Ranges

“…The performance of the translator is defined in a significant way by the effective bandwidth [10], [11]. While the translation of low-rate single-channel communication can, in principle, be accomplished by cavity-aided crystalline devices [16], [17], a general UBT should be capable of mapping the entire WDM band.…”

“…An attempt to increase the effective interaction length by enclosing the nonlinear crystal within a resonant cavity effectively limits the translated bandwidth [18]. Transverse PCF engineering makes it possible to synthesize nearly arbitrary dispersion profiles, which are required for phase matching between distant signal and pump waves [9]- [11]. More importantly, a rigorous dispersion control is combined with high confinement, providing an elevated nonlinear response (γ).…”

Nonlinear parametric resonances in quasiperiodic dispersion oscillating fibers

“…In the presence of a high power continuous wave (CW), MI leads to the emergence and amplification of gain sidebands in the wave spectrum. In nonlinear fiber optics, such a process has been demonstrated in fibers with anomalous, constant group velocity dispersion (GVD) [3], as well as in normal GVD fibers by enabling the fulfillment of the nonlinear phase-matching condition through either fourth order dispersion [4,5], birefringence or a multimodal structure [6][7][8]. However, the efficiency of such parametric processes may highly suffer from unwanted longitudinal fluctuations of the fiber parameters, with a rapid drop of the gain as well as a broadening of its bandwidth.…”

“…However, the efficiency of such parametric processes may highly suffer from unwanted longitudinal fluctuations of the fiber parameters, with a rapid drop of the gain as well as a broadening of its bandwidth. Ultimately, parametric gain may fully disappear in the presence of fiber fluctuations [4,5,[8][9][10], which leads to the requirement of sophisticated devices or fiber designs [11]. The efficiency of pulse reshaping processes may also be seriously impaired by stochastic fluctuations of the fiber parameters [12].…”

Tailoring the dispersion properties of photonic crystal fibers

“…In recent years, the supercontinuum applications have matured and expanded into new wavelength regimes (Domachuk et al 2007). At the same time, the use of PCFs for dispersion management (Avdokhin et al 2003;Lim et al 2002;Lim and Wise 2004;Nielsen et al 2006) and pulse compression (De Matos et al 2003;Limpert et al 2003;Lim and Wise 2004) in short-pulsed fiber lasers, as well as various applications within parametric amplification (Andersen et al 2004;de Matos et al 2004;Wong et al 2005), have been investigated by a number of authors.…”
