Wireless Power Transfer via Strongly Coupled Magnetic Resonances
TLDR
A quantitative model is presented describing the power transfer of self-resonant coils in a strongly coupled regime, which matches the experimental results to within 5%.
Deep learning with coherent nanophotonic circuits
TLDR
A new architecture for a fully optical neural network is demonstrated that enables a computational speed enhancement of at least two orders of magnitude and three order of magnitude in power efficiency over state-of-the-art electronics.
Tunable Efficient Unitary Neural Networks (EUNN) and their application to RNNs
TLDR
This work presents a new architecture for implementing an Efficient Unitary Neural Network (EUNNs), and finds that this architecture significantly outperforms both other state-of-the-art unitary RNNs and the LSTM architecture, in terms of the final performance and/or the wall-clock training speed.
Bound states in the continuum
Bound states in the continuum (BICs) are waves that remain localized even though they coexist with a continuous spectrum of radiating waves that can carry energy away. Their very existence defies
Observation of unidirectional backscattering-immune topological electromagnetic states
TLDR
It is demonstrated that, like their electronic counterparts, electromagnetic CESs can travel in only one direction and are very robust against scattering from disorder; it is found that even large metallic scatterers placed in the path of the propagating edge modes do not induce reflections.
Observation of trapped light within the radiation continuum
TLDR
It is predicted and shown experimentally that light can be perfectly confined in a patterned dielectric slab, even though outgoing waves are allowed in the surrounding medium.
Reflection-free one-way edge modes in a gyromagnetic photonic crystal.
TLDR
It is shown that the TM modes in a gyromagnetic photonic crystal can be formally mapped to electronic wave functions in a periodic electromagnetic field, so that the only requirement for the existence of one-way edge modes is that the Chern number for all bands below a gap is nonzero.
Low-loss asymptotically single-mode propagation in large-core OmniGuide fibers.
TLDR
The light-propagation characteristics of OmniGuide fibers, which guide light by concentric multi-layer dielectric mirrors having the property of omnidirectional reflection, are presented, promising that the properties of silica fibers may be surpassed even when nominally poor materials are employed.
Simultaneous mid-range power transfer to multiple devices
Electromagnetic resonators strongly coupled through their near-fields [A. Karalis, J. D. Joannopoulos, and M. Soljacic, Ann. Phys. 323, 34 (2008); A. Kurs, A. Karalis, R. Moffatt, J. D. Joannopoulos,
