Abstract

We have successfully demonstrated a simple and cost effective scheme for all-optical packet contention resolution by means of a PEDC comprised of a saturable absorber-based VCSG and a SOA. An extinction ratio of 15 dB for the PEDC output signal was measured with 1.5 ns using time and 2.5 ns falling time. Major benefits of our solution are polarization independence, transparency to the input packet wavelength, compactness, reduced number of active devices and low power operation
