We demonstrate transmission of 16 WDM channels at 10 Gbit/s with 50 GHz channel spacing over 3 times 80 km NZDSF, with small OSNR penalty, using only a single Raman-pumped dispersion compensating module positioned before the receiver.
Using an accurate full-vectorial finite element method, a realistic model of a fabricated dispersion compensating photonic crystal fiber is analyzed. An almost flat Raman-gain spectrum (gain-ripples at just plusmn0.48-dB) is obtained using a single pump.
All-fiber chirped-pulse amplification based on a large-mode-area Er:Yb-doped photonic-crystal fiber is presented. A dispersion-variable hybrid fiber stretcher compensates the peculiar dispersion of the hollow-core photonic-bandgap fiber compressor yielding transform-limited 440-fs pulses with 1-W average power.
Direct-detection differential polarization-phase-shift keying is experimentally demonstrated at 10 Gsymbol/s, in which polarization-phase symbols are differentially decoded by using optical interferometric demodulation and electrical multilevel decision without the need of dynamic polarization control.
We experimentally demonstrate a stimulated Brillouin scattering free, all fiber phase conjugator using 1-m length of our fabricated bismuth oxide-based nonlinear fiber. Using the conjugator, error-free, dispersion compensated transmission of a 10-Gbit/s NRZ signal over a 150 km SMF transmission link is readily achieved.
Scattering of a dispersive wave on a soliton in a cobweb PCF resulting in generation of new spectral components is observed directly with XFROG technique. Recent analytical theory and numerical modeling confirm the results.
We show an enhanced effect of cross-phase modulation with a Raman amplifier configuration. High performance wavelength conversion of 10 Gb/s non-return-to-zero signal is demonstrated with cross-polarization-modulation and Raman enhancement.
An analytic model of chirped-pulse amplification is presented. The model is used to optimize the peak power in fiber chirped-pulse amplification, in which the interplay of nonlinearity and third-order dispersion plays a major role.
Parabolic pulses from a similariton amplifier at 1550 nm are compressed using optimized linear compression in photonic bandgap fiber and soliton effect compression in dispersion-flattened highly nonlinear fiber. Transform-limited 20 fs pulses are obtained.
Pulse propagation in Er3+-doped fiber amplifiers (EDFA) is studied within the framework of a spectrally-resolved pulse rate-propagation equations model. Calculated pulse spectrograms demonstrate the effects of dispersion on sub-picosecond pulse propagation in EDFAs.
