80 GSPS photonic analogue to digital conversion system using broadband continuous wave source
ABSTRACT An 80 GSPS photonic ADC system is demonstrated, using broadband mode-locked lasers (MLL) and dispersive fibre to form a continuous waveform with time-wavelength mapping, and array waveguide gratings (AWG) to channelise. Tests are carried out for RF signals up to 10 GHz.

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/sMicrowave Photonics, 1999.
