100-GS/s 5-Bit Real-Time Optical Quantization for Photonic Analog-to-Digital Conversion

Below 100-fs Timing Jitter Seamless Operations in 10-GSample/s 3-bit Photonic Analog-to-Digital Conversion

“…Fig. 1 shows the schematic diagram of the proposed photonic ADC [6]- [10]. In an optical sampling part, sampling pulses and an input ultrawide-bandwidth analog signals are entered into a lithium niobate intensity modulator (LN-IM).…”

“…To address the energy efficiency, it is necessary to explore some serial approaches to get most of operations in a photonic ADC done before serial-to-parallel conversion to save power consumption. To press forward with the work on subsequent operations after optical sampling in a photonic ADC, we have investigated optical quantization and coding and demonstrated their performances [6]- [10].…”

Mid-infrared supercontinuum generation and its application on all-optical quantization with different input pulses*

“…[26] The AOADC, which aims to overcome the drawbacks of electrical ADC, has attracted considerable attention. [27][28][29][30][31] As the key process of AOADC, many smart schemes of alloptical quantization techniques determining the speed and res-olution of conversion were proposed with nonlinear optical effects in optical fibers, [28][29][30][31][32][33][34][35][36] while the vast majority of mature schemes pertaining to optical quantization employ soliton selffrequency shift (SSFS). [32][33][34][35][36] SCG in nonlinear media is an intensity-to-wavelength conversion of the input pulse, [37][38][39][40] and it is feasible for application in all-optical quantization.…”
