This letter reports on the use of a novel photonic integrated circuit that facilitates multicast and grooming in an optical data center architecture. The circuit allows for on-chip spatial multiplexing and demultiplexing as well as fiber core switching. Using this device, we experimentally verify that multicast and/or grooming can be successfully performed along the full range of output ports, for different group sizes and different power ratios. Moreover, we experimentally demonstrate SDM transmission and 5 Tb/s switching using the on-chip fiber switch with integrated fan-in/fan-out devices and achieve error-free performance (BER $\,\leq \, 10^{\mathrm {\mathbf {-9}}}$ ) for a network scenario, including simultaneous unicast/multicast switching and traffic grooming.
