Abstract
In order to meet the demand for highly scalable and energy efficient data center switches, multiplane architectures, where multiple optical switching domains are leveraged, are an attractive solution. In this scenario, the orbital angular momentum (OAM) of light can be exploited as an additional domain along with wavelength, space, and time. In this paper, we report the demonstration of an OAM-wavelength photonic integrated packet switch controlled by a field-programmable gate array (FPGA) implementing a two-step scheduler suited for multiplane architectures. Packet-based bit error rate (BER) measurements show transmission at 20 Gb/s with BER
