observation of incoherently coupled dark bright vector solitons in Single Mode Fibers
Optics Express, 2019Co-Authors: Xiaonan Hu, G D Shao, Yufeng Song, Boris A Malomed, Dingyuan TangAbstract:We report experimental observation of incoherently coupled dark-bright vector solitons in Single-Mode Fibers. Properties of the vector solitons accord well with those predicted by the respective systems of incoherently coupled nonlinear Schrodinger equations. To our knowledge, this is the first experimental observation of temporal incoherently coupled dark-bright solitons in Single-Mode Fibers.

broad band transmitted intensity noise induced by stokes and anti stokes brillouin scattering in Single Mode Fibers
IEEE Photonics Technology Letters, 1997Co-Authors: M Horowitz, R.w. Tkach, A R Chraplyvy, J L ZyskindAbstract:We experimentally investigate the optical noise induced by stimulated Brillouin scattering (SBS) in Single-Mode Fibers. The noise, which is caused by the random nature of spontaneous Brillouin scattering, is induced in the transmitted wave as well as in the backward Brillouin wave. In Fibers where the Brillouin gain spectra consist of several resonances, the induced intensity noise of the transmitted wave has a wide spectrum and it may be the dominant noise in the receiver for a broad radio frequency band (0-1 GHz). This unexpected result is explained by a multiple scattering process which is caused by stimulated and by thermally excited phonons. The SBS induced noise may cause a performance degradation in analog optical systems which require high optical powers and low noise. Using Fibers with a Single Brillouin resonance may limit the noise to lower frequencies.

Distributed Mode Coupling Measurement Along Tapered Single-Mode Fibers With Optical Frequency-Domain Reflectometry
Journal of Lightwave Technology, 2012Co-Authors: Xiaozhen Wang, Liang Chen, Xiaoyi BaoAbstract:We present the measurement of distributed Mode coupling along tapered Single-Mode Fibers using optical frequency-domain reflectometry. The energy re-distribution through Rayleigh backscatter amplitude as a function of distance with a 13 μm resolution over the whole taper region is measured. The wavelength shifts between the fundamental Mode and high order Modes of the taper are theoretically derived and experimentally verified by using autocorrelation data processing. An accurate measurement of refractive index differences in both gentle and abrupt tapers is achieved with a spatial resolution of ~2 cm. The measured results and theoretical values match well in gentle taper. It is found that the physical length of Mode coupling of abrupt taper is longer than its geometric length, while both lengths are the same in gentle taper. The measurement is rapid, repeatable and nondestructive.

characterization of the brillouin loss spectrum of Single Mode Fibers by use of very short 10 ns pulses
Optics Letters, 1999Co-Authors: Xiaoyi Bao, Anthony W Brown, Michael D Demerchant, Jeff SmithAbstract:The characterization of the Brillouin-loss spectrum of Single-Mode Fibers with very short <10?ns pulses has been studied. It was found that the Brillouin-loss signal intensity is linearly related to the duration of the pump pulse used to obtain the spectrum. In contrast with the uniform trend of the signal, three distinct behaviors were observed in the spectral linewidth. At long pulse durations the linewidth was constant at approximately 40??MHz. Pulse durations of the order of the phonon lifetime resulted in a broader spectrum, reaching a maximum width of ?100 MHz at 5??ns. Reducing the pulse duration further resulted in a sudden narrowing of the Brillouin line.

supercontinuum generation by noise like pulses transmitted through normally dispersive standard Single Mode Fibers
Optics Express, 2013Co-Authors: Alexey Zaytsev, Chihhsuan Lin, Yijing You, Chiachun Chung, C H Wang, Ciling PanAbstract:We report generation of broadband supercontinuum (SC) by noise-like pulses (NLPs) with a central wavelength of 1070 nm propagating through a long piece of standard Single-Mode Fibers (~100 meters) in normal dispersion region far from the zero-dispersion point. Theoretical simulations indicate that the physical mechanism of SC generation is due to nonlinear effects in Fibers. The cascaded Raman scattering is responsible for significant spectral broadening in the longer wavelength regions whereas the Kerr effect results in smoothing of SC generated spectrum. The SC exhibits low threshold (43 nJ) and a flat spectrum over 1050-1250 nm.

Comparative study of the effective Single Mode operational bandwidth in sub-wavelength optical wires and conventional Single-Mode Fibers.
Optics express, 2009Co-Authors: Yongmin Jung, Gianfranco Brambilla, David J RichardsonAbstract:We present the first experimental comparison of effective Single Mode operation bandwidth in sub-wavelength optical wires (SOWs) and conventional Single-Mode Fibers (SMFs). The full transmission spectrum, half-turn bend loss and Mode field diameter were measured and compared for a variety of SMFs of different cut-off wavelength and a SOW. The SOW was shown to offer an enormously broadband Single-Mode operation bandwidth with a larger Mode field area than the SMFs. Applications of SOWs include fiber lasers, sensors, photolithography and optical coherence tomography amongst others.
