"From Optical Communications to the Brain: Integrated 3D Silicon Photonics"
Joyce Poon

Abstract

Foundry-manufactured, monolithically integrated multilayer silicon nitride-on-silicon photonic platforms are suitable for large-scale photonic circuits.  These photonic platforms contain several waveguide layers, and light is routed amongst the layers to create 3D photonic devices and circuits.  We have realized a suite of devices in these platforms, including ultra-low-loss waveguide crossings, multi-layer grating couplers, and efficient modulators.  These advancements, which were initially driven by telecommunications, are leading to neurophotonic implants for brain activity mapping.

"Next-generation organic electro-optic materials for hybrid device architectures"
Gerard Zytnicki, Lewis Johnson and Paul Nye
(Nonlinear Material Corporation, Seattle, Washington)

Abstract

Next-generation silicon-organic hybrid (SOH) and plasmonic-organic hybrid (POH) device architectures have led to renewed interest in organic electro-optic (OEO) materials for chip-scale photonic integration under a different set of design constraints than for bulk devices. State-of-the art hybrid devices are capable of 10x the electro-optic activity of LiNbO3 and far superior device footprints, power efficiency, and signal quality to competing device architectures. Fully realizing the multiple order of magnitude reduction in modulator size from advances in hybrid devices will require development of materials with exceptional electro-optic activity and refractive indices that have been optimized for these device architectures. Multiscale modeling, combining classical condensed-phase simulations and electronic structure theory, has provided many crucial observations that suggest how to design the next generation of OEO molecules. We apply a variety of computational techniques to identify bottlenecks to materials performance and develop routes for transformative improvement in electro-optic materials, in addition to leveraging insights in dendritic chromophore systems to improve thermal stability. Our calculations have already identified synthetically feasible materials predicted to yield > 2x performance improvements versus the state of the art and provide a pathway to order-of-magnitude improvement.

"Energy Efficient Silicon Modulators For Short-range Optical Interconnects"
Reza Hosseini

Abstract

“Slow-light effect at the band edge of corrugated waveguides is employed to enhance the modulator’s performance in terms of energy efficiency. The slow-light effect is studied in detail for one-dimensional photonic crystals namely, corrugated waveguides. It is shown such waveguides increase the induced phase shift in the modulator arms due to enlarged group index of the waveguides. It results in modulation efficiency reduction, which can ultimately lead to less energy consumption of the modulator as well. Electrical bandwidth of the modulators are also investigated. It is estimated that energy consumption can be reduced down to 100 fJ/bit at slow-down factor 6. An integrated silicon photonic MZM modulator with a slow-wave architecture to reduce is presented. This structure achieves an 80% enhancement in extinction ratio and has a 14 GHz bandwidth with 1 mm long modulator arms.”
