All-optical M-ary ASK Signal Demultiplexer Based on Photonic Analog-to-digital Conversion With Bitwise Signal Allocation

摘要

We propose and demonstrate the all-optical M-ary ASK signal demultiplexer based on photonic analog-to-digital conversion with bitwise signal allocation. Experimental result shows that the quaternary ASK signal can be successfully demultiplexed into two 25 Gb/s OOK signals.
