Power Scaling of InP based Photonic Crystal Surface Emitting Lasers for CWDM Optical Interconnects in Hyperscale Datacenters

Abstract

We demonstrate power scaling of InP substrate emitting PCSELs by increasing device size. A maximum power of 713mW was obtained. We attribute improved slope efficiency of larger devices to reduced in-plane loss. These devices are suitable for integration into hybrid, co-packaged optical transceivers in datacenters.
