摘      要：All-optical 1 ×4 broadcast and 1 ×3 multicast experiments of a 40-Gb/s return-to-zero on-off keying （RZ- OOK） signal based on a periodically poled lithium niobate （PPLN） waveguide are demonstrated in this letter. Clear opened eye diagrams and error-free performance are achieved for the broadcast signals at 1541.3, 1543.7, 1548.5, and 1550.9 nm. Multicast technology uses cascaded second-harmonic generation and difference-frequency generation in a Ti：PPLN waveguide. An error-free operation with a negligible power penalty is achieved for the three wavelength-division multiplexing multicast signals at 1533, 1537, and 1541 nm.
