Building on low jitter mode-locked lasers, joint electrical-optical signal processing in analog-to-digital converters enables both ultra-wideband and ultra-low-noise signal acquisition. In PACE, we are investigating novel integrated time-interleaved and frequency-sliced photonically assisted analog-to-digital converters aimed at surpassing the current state-of-the-art analog-bandwidth-resolution product. In addition to the data-converters themselves, integrated solution for low jitter comb sources are also pursued, with the objective to provide a complete solution towards full system integration. Building on the accomplishments of the first phase, the bandwidth of frequency-sliced ADCs will be increased above 400 GHz based on a chip-scale optical engine. Time-interleaved ADCs will leverage novel optically triggered track-and-hold amplifiers as well as opto-electronic phase-locked loops developed in the first project phase. Rare-earth on-chip mode-locked lasers will serve as a reference to long term stabilize semiconductor mode-locked lasers, thus upconverting their repetition rate while maintaining low jitter operation. Novel capacitively coupled silicon-organic hybrid electro-optic modulators will be advanced with respect to bandwidth and benchmarked against ultra-broadband thin-film lithium niobate devices developed in the context of the project.

在低抖动锁模激光器的基础上，模数转换器中的联合电光信号处理实现了超宽带和超低噪声信号采集。在PACE中，我们正在研究新型集成时间交错和频率切片光子辅助模数转换器，旨在超越当前最先进的模拟带宽分辨率产品。除了数据转换器本身，还追求低抖动梳状源的集成解决方案，目标是提供一个完整的解决方案，实现全面的系统集成。在第一阶段成果的基础上，基于芯片级光引擎的频率分片ADC的带宽将提高到400 GHz以上。时间交错ADC将利用第一个项目阶段开发的新型光触发采样保持放大器以及光电锁相环。稀土片上锁模激光器将作为长期稳定的半导体锁模激光器的参考，从而在保持低抖动操作的同时上转换其重复频率。新型电容耦合硅-有机混合电光调制器将在带宽方面取得进展，并以该项目背景下开发的超宽带薄膜锂酸盐器件为基准。
