Strong spin-orbit interaction can be induced by light-bending metasurfaces. We show that the photon spin momentum can be directly transferred to collective motion of electrons on a conductive metasurface with this interaction.
We experimentally demonstrate a novel approach based on adiabatic elimination scheme to control the coupling between densely packed waveguides. At the nano-scale, cancellation of the coupling between the waveguides can be achieved.
We introduce a new method to localize lightwaves. We show how the interaction of a gain medium with a planar deep-UV plasmonic heterostructure, at its zero-vg point, strongly localizes light. A quantum-coherent drive provides a means to control the localization and dramatically improve the dynamics.
The ubiquitous spin-orbit interaction destroys the particles' spin rotational symmetry and introduces a universal transverse spin current. Here we show that an anomalous refracting metasurface induces a controllable spin-orbit interaction and a path-dependent polarization rotation.
We demonstrate an electrically controllable light-matter interaction in a gate-controlled active graphene terahertz metamaterial, which shows an electrically controlled memory effect as well as the modulation of terahertz waves in the extreme subwavelength-scale.

Exceeding the Shockley-Queisser efficiency limit for a single junction solar cell has been theorized using various means. Specifically, up- and down-conversion, carrier multiplication and intermediate band transitions have been posited as methods of improving the efficiency. Here, we compare these methods using a thermodynamic approach with a newly devised pseudo-linear system model. This method allows...
In this paper, we propose PROPEL, a photonic network-on-chip (NoC) that improves performance and power with energy-efficient opto-electronic components for future chip multiprocessors (CMPs). Our analytical and simulation results indicate that PROPEL improves throughput and reduces power over optical and electrical networks for various traffic traces while requiring fewer photonic components and devices.
