Fig. 3: Experimental results and error rate values for the validation of the 2-symbol vector comparison, at 20 and 50 Gb/s operational data rates.

a Synchronized time traces (50 ps/div) showing 10 encoded search bits (Bit1-Bit2) along with the respective comparison outcomes with the target vector cases of “00”-“XX”. b Corresponding eye diagrams at 20 Gb/s operation. c Synchronized time traces (20 ps/div) of 10 optically encoded search bits (Bit1-Bit2) and comparison contents. d Εye diagrams at 50 Gb/s operation. e Error-rates of all cases at 20 Gb/s. f Error rates when the processor operates at 50 Gb/s.
