Figure Lengend Snippet: a Experimental setup of the PRTC demonstration. CW laser continuous-wave laser, PC polarization controller, AWG arbitrary waveform generator, FPGA field programmable gate arrays, PD photodetector. b , c Experimental output results of random input at 16GS/s. d Scatter plot for computing accuracy measurement with 4 sets of 10,000 random inputs. e Histogram of compute errors over 10,000 data samples.
Article Snippet: The voltages applied to the thermal phase shifters are provided by the digital-to-analog converter (LTC2688), which is controlled by a field programmable gate array chip (Xilinx 7K325T).
