A nonlinear index guiding silica PCF is optimized for efficient second harmonic generation through dispersion calculations zero group velocity mismatch is possible for any pump wavelength above 80 nm. Very high conversion efficiencies and bandwidths are found.
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.
We present experimental and theoretical investigation of modulation instability process in large normal dispersion regime leading to visible continuum generation. The influence of the input power and polarization state of the pump wavelengths are analyzed.
A four-sideband stochastic analytical model is developed to investigate the impact of random fluctuations of the zero dispersion wavelength on two pump fiber-optic parametric processes. Theoretical predictions are in an excellent agreement with experimental results.
We demonstrate DPSK wavelength multicasting using four-wave mixing in a 64-m dispersion-flattened photonic crystal fiber. Six multicast channels operating at 10 Gb/s are obtained at a 200 GHz spacing.
We demonstrate the production of a well depleted mid-IR continuum with a spectral range between ~0.9 - 2.5 mum using a tellurite wagon wheel microstructured fiber and a pump source at 1.5 mum.
