All-optical wavelength-/time-selective switching/dropping/swapping for 100-GHz-spaced WDM signals using a periodically poled lithium niobate waveguide

摘要

By exploiting sum-frequency generation or cascaded sum- and difference-frequency generation in a periodically poled lithium niobate waveguide, we demonstrate wavelength-/time-selective switching/dropping/swapping. It is shown these operations are applicable for 100-GHz-spaced WDM signals owing to the narrow-band quasi-phase matching condition.
