Abstract: Optical sampling pulses generated by cascade modulators have been widely studied for broadband signal acquisition in photonic analog-to-digital converters (PADCs). In this paper, we establish a comprehensive theoretical optical sampling model that incorporates the photodetection-induced… read more here.
