Experimental Demonstration of 51.2 Tb/s Self-Homodyne Coherent Interconnects on a 3D Photonic Chip Inspiring Coherent Technology Transfer to Centimeter-Scale Ultra-Short-Reach Applications

We demonstrated a record net 51.2 Tb/s (800Gb/s PDM-64QAM x 64 Channels) ultrafast laser inscribed 3D photonic chip interconnects based on self-homodyne coherent detection, showing the feasibility of coherent technology transfer to ultra-short-reach applications.
