An 80-Gbit/s soliton can be transmitted over a cross-Pacific distance in a dense periodic fiber, even in the presence of higher-order effects. Such a dense dispersion-managed soliton is generallyâ€¦ (More)

For weakly guiding noncircular single-mode waveguides, we define the generalized frequency v and find that the four parameters [v, b(v), d(vb)/dv, vd(2)(vb)/dv(2)] play an important role in theâ€¦ (More)

Four-wave mixing in dense periodic fiber is much less than in conventional dispersion management and constant-dispersion systems over a wide wavelength range, including the resonant wavelength.

The gain and noise figure can be improved by periodic bending of an erbium-doped fiber. Bending of 5.4 m at the beginning of an erbium-doped fiber results in a reduction of noise figure, a gainâ€¦ (More)

It is proved that three mode-field-radius definitions, W(rms), W(L), and W(G), for arbitrary circularly symmetric, singlemode fiber are related as W(rms) >/= 2 W(G) >/= W(L), and the equal signâ€¦ (More)

We derive an approximation for the transverse offset loss based on the Laplacian mode-field half-width (MFHW) and far-field second moment for two arbitrary identical noncircular single-modeâ€¦ (More)
