Synthetic materials with high pockels coefficient for plasmonic modulators Open
We present simulations of Pockels materials based on nonlinearities arising from intersubband transitions (ISBT). To elevate the Pockels coefficient to the order of nm/V, the ISBT resonance is tuned close to the operation point. This comes…

Metamaterial graphene photodetector with bandwidth exceeding 500 gigahertz Open
Although graphene has met many of its initially predicted optoelectronic, thermal, and mechanical properties, photodetectors with large spectral bandwidths and extremely high frequency responses remain outstanding. In this work, we demonst…

Nano–opto-electro-mechanical switches operated at CMOS-level voltages Open
Switching light on-chip The development of practical, reconfigurable photonics requires a platform that can be scaled to large circuits and driven by low-voltage complementary metal-oxide semiconductor (CMOS) electronics. Such a platform r…

Low-loss hybrid plasmonic coupler Open
We demonstrate a low-loss coupling scheme between a silicon photonic waveguide and a hybrid-plasmonic waveguide. Measured coupling efficiencies reach up to 94% or -0.27 dB. The metal-insulator-semiconductor structure is fabrication-toleran…

GHz Rotation of an Optically Trapped Nanoparticle in Vacuum Open
We report on rotating an optically trapped silica nanoparticle in vacuum by transferring spin angular momentum of light to the particle's mechanical angular momentum. At sufficiently low damping, realized at pressures below 10^{-5} mbar, w…
