摘要

All-optical 1 ×4 broadcast and 1 ×3 multicast experiments of a 40-Gb/s return-to-zero on-off keying (RZOOK) 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.
