Abstract :
In this paper we present a 12 Gsample/s continuous-time wavelength division ADC system. The system uses the recirculating photonic filter true-time-delay (TTD) for dispersion-free chirp generation. It can digitize continuous-time analog signals at 12 Gsample/s using three wavelength channels at 4Gsample/s and three real-time electronic digitizers operating at 4Gsample/s
