“…Significant increase of the pulse energy has been realized by using parabolic pulses [1,2] and, more recently, all-normal-dispersion cavities [3,4]. Another area of intense investigation is the realization of frequency combs [5,6], for which stable, multi-wavelength operation is needed in view of applications such as dense wavelength-division multiplexing [7] or optical metrology [8]. Highrepetition-rate fiber lasers naturally deliver such frequency comb distributions [9].…”

“…It potentially provides a wider frequency comb and, more importantly, it allows to get rid of the custom nonlinear Mach-Zehnder. FWM has been studied extensively for the generation of optical frequency combs [35][36] [37]. In particular, zero-dispersion-slope highly nonlinear fibers (HNLF) are now available and offer many advantages in terms of efficiency and easy integration.…”

“…No campo de amplificação em sistemas RoF, fibras altamente nãolineares (HNLF -highly nonlinear fiber) são utilizadas para intensificar o FWM. Estas fibras tipicamente possuem altos coeficientes de não-linearidade (γ) bem como comprimento de onda de dispersão nula (λ 0 ) na janela de transmissão [11]. Complementarmente, elevadas potências de bombeio são utilizadas para melhorar a eficiência na geração de produtos FWM.…”
