Paper Abstract

We experimentally demonstrate a novel decimal optical buffer scheme based on multi-loop configuration and single switch element--an optical crosspoint switch (OXS) matrix. Our results show that by using a differential phase-shift keying (DPSK) payload in the buffer can outperform OOK payload with 3.2 dB sensitivity improvement owing to its alleviation of patterning induced degradation compared to OOK payload, clearly validating DPSK as a promising modulation format to overcome nonlinear impairments and to extend number of hops in all-optical packet switching network.
