Soliton Molecules Bind in a Kerr Micro-Ring for Light Control
Light can behave like a stubborn rumor that stubbornly refuses to fade. In tiny rings made of a nonlinear optical material, pulses of light can lock into a single, self-sustaining shape—called a soliton—that travels without spreading. When designed just right, these solitons balance dispersion, nonlinearity, gain, and loss, forming stable, localized packets that persist as…
