title: Dark solitons in degenerate optical parametric oscillators.
abstract: It is shown theoretically that a degenerate optical parametric oscillator with a frequency limiter and continuouswave pumping can generate stable dark solitons when it operates near antiresonance. These solitons are supported by the combined effect of pump depletion and spectral filtering, and their stability is ensured by the phase-dependent nature of the parametric gain.
