Localized high-Q resonances enable electrically defined beam steering in lithium niobate metasurfaces
Jiyong Shim, Sahil Dagli, Hamish Carr Delgado +7
High-speed beam steering for LiDAR and optical communication requires independent, reconfigurable control of optical phase. We demonstrate a metasurface combining lithium niobate's…
Nonresonant optomechanical control of structural phases
Jiaojian Shi, Yijing Huang, Christian Heide +24
Optical tweezers demonstrate how light can exert forces to trap, repel, and manipulate microscopic particles without absorption. Recent theory has suggested that such forces can ex…
Temperature-dependent excitonic light manipulation with atomically-thin optical elements
Ludovica Guarneri, Qitong Li, Thomas Bauer +5
Monolayer 2D semiconductors, such as WS2, exhibit uniquely strong light-matter interactions due to exciton resonances that enable atomically-thin optical elements. Similar to geome…
Acoustic wave modulation of gap plasmon cavities
Skyler P. Selvin, Majid Esfandyarpour, Anqi Ji +5
The role of metallic nanostructures in nanophotonics is expected to expand if ways to electrically manipulate their optical resonances at high speed can be identified. Here, we cap…
Apparent Resonance Splitting in Self-Coupled Excitonic Systems
Avishek Sarbajna, Qitong Li, Dorte Rubæk Danielsen +6
Thin films of high-refractive-index excitonic materials enable self-coupling by simultaneously supporting intrinsic excitonic transitions and optical resonances. These optical reso…
GHz-speed wavefront shaping metasurface modulators enabled by resonant electro-optic nanoantennas
Sahil Dagli, Jiyong Shim, Hamish Carr Delgado +12
Electrically tunable metasurfaces that control the amplitude and phase of light through biasing of nanoscale antennas present a route to compact, sub-micron thick modulator devices…
Highly efficient, tunable, electro-optic metasurfaces based on quasi-bound states in the continuum
Christopher Damgaard-Carstensen, Torgom Yezekyan, Mark L. Brongersma +1
Ultrafast and highly efficient dynamic optical metasurfaces enabling truly spatiotemporal control over optical radiation are poised to revolutionize modern optics and photonics, bu…
Tensile-Strained Germanium-on-Insulator Substrate Fabrication for Silicon-Compatible Optoelectronics
J. Raja Jain, Dany-Sebastien Ly-Gagnon, Krishna C. Balram +4
We present a method to fabricate tensile-strained germanium-on-insulator (GOI) substrates using heteroepitaxy and layer transfer techniques. The motivation is to obtain a high-qual…
