We will first describe the infrastructure challenges and use cases that motivated optical switching inside datacenters.
WebThe paper presents an optical circuit switching network architecture and its control and traffic scheduling schemes. This optical switch network is built on a 32×32 AWG and fast wavelength tunable transmitters and is able to support up to 128 interface ports. The feasibility of the architecture is verified through an experimental study. Next, integrated Indium phosphide (InP) chip-based SOAs and AWG are used to show 25-Gbps NRZ burst mode data transmission along with fast OCS using a soliton microcomb. Figure 4b shows the photonic integrated circuit (PIC) based wavelength selector PIC with a dimension of 6 mm × 8 mm. The reflection of … See more Figure 1 shows the OCS architecture containing the soliton microcomb, SOAs, AWGs in the switch and AWGRs to route the data across many racks (cf. Methods). … See more For a proof-of-concept system-level demonstration, fast switching within four different comb channels is performed. Figure 2e shows sub-ns switching between four … See more
