We demonstrate multiple pattern recognitions in a 1- and 3-Gbaud QPSK inputs using intra-symbol time multiplexing and nonlinear wave mixing. The concept is experimentally validated, where the pattern-matching occurrences are represented by the top-right symbol of the output constellation for each pattern.
