Talk title: Integrated optomechanical and superconducting quantum circuits
Talk abstract: I will present recent work at Caltech on the integration of optomechanical crystals for light and sound with electronic superconducting quantum circuits. Utilizing the silicon-on-insulator (SOI) wafer platform, we have made key advances in the fabrication and integration of extremely low loss microwave phonon structures and low loss microwave superconducting resonators of high impedance. These technical advancements offer several intriguing opportunities for quantum information processing and networking with phonons, photons, and electrons in an integrated, wafer-scale platform. The focus of my talk will be on two examples of our efforts in this direction: (i) nonreciprocal photon transport and amplification arising from synthetic magnetic flux and reservoir engineering in an optomechanical crystal circuit, and (ii) waveguide-QED systems consisting of microwave-bandgap circuits with embedded transmon-like qubits.

Talk Title: Microscale Light Emitting Diodes: From Information Display to Discovery Tools in Neuroscience
Abstract: Recent advances in materials science and engineering provide means for constructing high-performance light emitting diodes with unusual sizes, shapes and forms and with efficient operation throughout the infrared, visible and ultraviolet. When combined with high-speed assembly techniques, microscale devices of this type can be configured onto ultrathin polymer filaments for injection into biological tissues, onto elastomeric substrates for use in skin-conformal health diagnostics, and into large-scale sparse arrays for high-speed displays with unmatched brightness, contrast, switching speeds and power efficiency. This talk summarizes the foundational scientific concepts and the engineering designs for these and other applications.

Talk title: Graphene for next generation silicon photonics
Talk abstract: We show that graphene can be provide electro-optic properties to traditionally passive optical materials and enable efficient integrated active nanophotonic devices. We show devices with GHz absorption modulation based on ring resonators. We also report the first experimental demonstration of a graphene electro-refractive modulator with VπL of 0.14 Vcm, and minimal absorption modulation based on graphene capacitor integrated on Si3N4 with embedded high-K and high breakdown dielectric.

Talk title: Plasmonics – a Path to Replace Photonics by a Scalable, Ultrafast Technology?
Talk abstract: Plasmonics is increasingly touted as a solution to replace traditional photonics. And indeed, a new generation of passive and active plasmonic elements is emerging. Unlike photonic devices these plasmonic elements feature a tiny footprint in combination with an almost unlimited bandwidth. Yet, plasmonic devices also suffer from high losses. The question then is where and when plasmonics really can make a difference. In this talk, we will review and comment the latest generation of plasmonic devices encompassing plasmonic electro-optical modulators, detectors, RF-receivers, couplers and waveguides and compare them against devices relying on the traditional silicon technology.
