Abstract

A broadband photonic time-stretch analog-to-digital converter (PTS-ADC) based on complementary parallel singlesideband (SSB) modulation architecture is proposed and experimentally demonstrated by using a dissipative soliton-based passively mode-locked fiber laser (MLL). The experiment results indicate that the proposed scheme can increase the effective input analog bandwidth and remove the pulse-envelope-induced distortion. The signal-to-noise ratio of the photonic time stretch system can be guaranteed by using the dissipative soliton-based MLL. Therefore, a broadband PTSADC with input frequency of 2GHz to 25 GHz is constructed and an ENOB of beyond 3 bits is achieved.
