Abstract
The observation of modulational instability of optical waves in the normal dispersion region has been accomplished through the copropagation of two nonlinearly coupled, orthogonally polarized visible waves in a strongly birefringent optical fiber. Intensity autocorrelations exhibit ∼3.5-THz oscillations on both waves, and each wave spectrum develops a single shifted frequency sideband. The results agree well with an analysis of coupled nonlinear Schrödinger equations.
