We describe the challenge of implementing optical interconnect for beyond Moore's electronic devices. In particular, we developed a simple link model and calculated the optical communications energy for logic voltages down to 10 mV. The results of this link model show a limit to the minimum communications energy that depends on the achievable extinction ratio of the devices. This work gives some insight...
We proposed a polymer 4×4 three-dimensional (3D) optical interconnection switch. The analysis shows colorless and polarization-independent operation. We fabricated the proposed device, and it successfully operated at 1550nm wavelength in quasi-colorless and polarization independence.
Datacenters are creating an unprecedented challenge for optical transceivers requiring multiple high performance lasers, modulators and photodiodes in a single module to meet growing bandwidth needs along with dramatically lower power and cost reflecting the higher volume and density of interconnections. The heterogeneous integration of InP material into a silicon photonics wafer flow enables high...
Optical interconnects play an integral role in large-scale digital computing, switching, and routing systems. The authors describe a path toward future many-chip modules based on silicon photonic interposers that stitch together tens of chips in a dense and efficient communication infrastructure. They review the guiding design principles for this "macrochip" and describe its canonical energy,...
We examine the complex relationship between experimentally-measured power penalty performance metrics of a silicon photonic modulator, and its broad impact on the throughput performance of a full-scale on-chip optical interconnection network. Using our physically-accurate network-level simulation environment, we further evaluate this impact from hypothetical device performance improvements. The results...
We present a computing microsystem that uniquely leverages the bandwidth, density, and latency advantages of silicon photonic interconnect to enable highly compact supercomputer-scale systems. We describe and justify single-node and multinode systems interconnected with wavelength-routed optical links, quantify their benefits vis-a-vis electrically connected systems, analyze the constituent optical...
