PUNCH offers a solution for time-deterministic and time-sensitive networks by developing a new optical switching paradigm which (I) breaks the trade-off between flexibility (ultra-dynamic reconfigurability) and determinism (guaranteed latency and jitter) by offering an all-to-all reconfigurable interconnect; (II) reduces congestion by activating bandwidth steering so that additional capacity can be allocated between hot nodes in the network; (III) provides unparalleled dynamics and bandwidth efficiency by further enabling multiplexing in the time domain with fast reconfigurable capability. A 2×2×8Lambda wavelength selective switching element will be scaled to a fully non-blocking 8x8x8Lambda and 16x16x8Lambda reconfigurable optical switch fabric. The development of a III-V foundry process for micro-transfer-printing-compatible semiconductor optical amplifiers enables loss-less optical switching on a silicon photonics platform. Custom configuration electronic ICs to actuate, control, and power-monitor a scaled switch fabric will be densely integrated with the photonic ICs into a heterogeneous fanout wafer-level package, processed on a 200mm reconstructed wafer platform. In addition, the optical interfacing to the photonic ICs will be accomplished using an optical redistribution layer, providing an optical fanout on high density organic substrates, and allowing for a scalable optical fiber packaging solution. The novel integration and packaging processes will be applied for manufacturing 1.6 Tbit/s optical transceivers providing the interface between optical switches and electronic resources (compute, memory, and storage). The optical switch and transceiver prototypes will be demonstrated in a 5G RAN Transport Network, for TSN Fronthaul applications and for memory disaggregation in data centers.

Pun通过开发新的光交换范例为时间确定性和时间敏感型网络提供了解决方案，该范例(I)通过提供全对全可重构互连打破了灵活性(超动态可重构)和确定性(保证延迟和抖动)之间的权衡；(Ii)通过激活带宽转向来减少拥塞，以便可以在网络中的热点节点之间分配更多容量；(Iii)通过进一步在具有快速可重构能力的时间域中实现多路复用来提供无与伦比的动态和带宽效率。2×2×8波长选择交换元件将扩展为完全无阻塞的8x8x8Lambda和16x16x8Lambda可重构光交换结构。用于微转移印刷兼容半导体光放大器的III-V铸造工艺的开发使硅光电子平台上的无损光学开关成为可能。用于驱动、控制和监控已扩展交换结构的定制配置电子IC将与光子IC紧密集成到异类扇出晶圆级封装中，并在200 mm重建晶片平台上进行加工。此外，与光子IC的光学接口将使用光学再分布层来完成，在高密度有机衬底上提供光学扇出，并允许可扩展的光纤封装解决方案。新的集成和封装工艺将应用于1.6TIT/S光收发器的制造，提供光开关和电子资源(计算、存储器和存储)之间的接口。光交换机和收发器原型将在5G RAN传输网络中演示，用于TSN Fronthaul应用和数据中心的内存分解。
