The energy consumption of manycore architectures is dominated by data movement, which calls for energy-efficient and high-bandwidth interconnects. To overcome the bandwidth limitation electrical interconnects, integrated optics appear as a promising technology. However, it suffers from high power overhead related to low laser efficiency, use techniques methods improve its costs. Besides, approx...
Photonic-integrated devices need to be adequately spaced apart to prevent signal cross-talk. This fundamentally limits their packing density. Here we report the use of nanophotonic cloaking to render neighbouring devices invisible to one another, which allows them to be placed closer together than is otherwise feasible. Specifically, we experimentally demonstrated waveguides that are spaced by ...
The realization of quantum networks critically depends on establishing efficient, coherent light-matter interfaces. Optically active spins in diamond have emerged as promising nodes based their spin-selective optical transitions, long-lived spin ground states, and potential for integration with nanophotonics. Tin-vacancy (SnV$^{\,\textrm{-}}$) centers are particular interest because they exhibi...
There are a range of fundamental challenges associated with scaling optoelectronic devices down to the nano-scale, and past decades have seen significant research dedicated development sub-diffraction-limit optical devices, often relying on plasmonic response metal structures. At longer wavelengths mid-infrared, dramatic changes in traditional nanophotonic materials, reduced efficiency active r...
Nanophotonic plasmon circuits may play important roles in next-generation information technology as semiconductor-based electronics is approaching the physical limit. The functions of such circuits rely on the rigorous control of plasmon propagation. One important aspect of such control is controlling the conversion of different plasmon modes for designed plasmon routing in complex nanophotonic...
The most general investigation and exploitation of light-induced processes require simultaneous control over spatial and temporal properties of the electromagnetic field on a femtosecond time and nanometer length scale. Based on the combination of polarization pulse shaping and time-resolved two-photon photoemission electron microscopy, we demonstrate such control over nanoscale spatial and ult...
