Dispersion and Brillouin Managed HNLFs by Strain Control Techniques

In this paper, we investigated a chromatic dispersion and Brillouin gain spectrum (BGS) control in highly nonlinear fibers (HNLFs). Downsized HNLFs (DS-HNLFs) with specific mechanical properties are effective to realize novel applications using a strain applied to the fibers. We experimentally demonstrated the zero dispersion wavelength (¿ 0 ) and the BGS tuning of the DS-HNLFs by the strain control technique. In addition, the efficient stimulated Brillouin scattering (SBS) suppression was also demonstrated by the dispersion and BGS managed downsized dispersion-decreasing HNLF. We confirmed that the efficiency of the wavelength conversion was increased drastically by the SBS suppression, and the maximum conversion efficiency of 1.5 dB was realized by a single continuous-wave pump without phase modulation.
