Abstract
We report the experimental demonstration of all-optical wavelength multicasting
of OC-768 (40 Gbps) channel using a single-pass, pump modulated parametric
amplifier. The performances of 1-to-20 and 1-to-40 multicasting with excellent
signal fidelity were observed. The impairment mechanisms were identified from
cascaded filtering, linear and nonlinear crosstalk. It is shown that the parametric
amplifier offers a wide range of operation characterized by minimal multicast
penalty. We show that all multicast channels have an error free performance
with Q factors well above the forward error correction (FEC) limit within
the designed operating range.
