Demonstration of a Large Stretch-Ratio (=41) Photonic Analog-to-Digital Converter With 8 ENOB for an Input Signal Bandwidth of 10 GHz

We report the demonstration of a time-stretch photonic analog-to-digital conversion (ADC) system with a stretch ratio of . By stretching a 10-GHz modulation envelope to 242 MHz via optical dispersion, we demonstrated, for the first time, an ADC resolution that is better than 8 effective number of bi...

Description
Summary:We report the demonstration of a time-stretch photonic analog-to-digital conversion (ADC) system with a stretch ratio of . By stretching a 10-GHz modulation envelope to 242 MHz via optical dispersion, we demonstrated, for the first time, an ADC resolution that is better than 8 effective number of bits for a 10-GHz input-signal bandwidth.
