We demonstrate a compact 4×4 wavelength selective switch with 50% fewer electrical signal pads as compared with our previous generation. We report loss and crosstalk for different paths of the switch. We measure median loss of 5.32 dB and worst case

Coherent optical links are becoming increasingly attractive for intra-data center applications as data rates scale. Realizing the era of high-volume short-reach coherent links will require substantial improvements in transceiver cost and power effici

Wavelength-selective switches have been proposed for datacenter use to enhance the scalability of their networks to help in meeting ever-increasing traffic demands. We have previously demonstrated a 4 × 4 ring-based crossbar silicon photonic switch

We present a new switching architecture that is wavelength selective and can multicast. We compare the switch loss, number of elements and crosstalk with multi-wavelength selective crossbar switch. We report reduction in number of elements of 50%, re

In this Letter, we present a new hybrid broadband-crossbar switching network that can switch multiple wavelengths on demand and can also multicast. This switch fabric is an improvement over our previous design in both switch footprint and power consu

We demonstrate a multi-wavelength selective crossbar switch with up to two wavelength switching capability per crosspoint. The switch has a mean path loss of 2.43 dB. We demonstrate an error free high speed PAM 4 transmission at 111.16 Gbps. We also
