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…
Factors Exceeding in Wavelength-to-Subwavelength-Scale Free-Space Resonators
Darrell E. Omo-Lamai, Varun Dolia, Yanyu Xiong +7
Free-space-addressable optical resonators that combine long photon lifetimes (high factors) with strong spatial localization of optical fields (small mode volumes, ) enhan…
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…
High-throughput antibody screening with high-quality factor nanophotonics and bioprinting
Sajjad Abdollahramezani, Darrell Omo-Lamai, Gerlof Bosman +12
Empirical investigation of the quintillion-scale, functionally diverse antibody repertoires that can be generated synthetically or naturally is critical for identifying potential b…
Room-temperature valley-selective emission in Si-MoSe2 heterostructures enabled by high-quality-factor chiroptical cavities
Feng Pan, Xin Li, Amalya C. Johnson +14
Transition metal dichalcogenides possess valley pseudospin, enabling coupling between photon spin and electron spin for classical and quantum information processing. However, rapid…
Very-Large-Scale-Integrated High- Nanoantenna Pixels (VINPix)
Varun Dolia, Halleh B. Balch, Sahil Dagli +9
Metasurfaces provide a versatile and compact approach to free-space optical manipulation and wavefront shaping. Comprised of arrays of judiciously-arranged dipolar resonators, meta…

High quality factor silicon-on-lithium niobate metasurfaces for electro-optically reconfigurable wavefront shaping
Elissa Klopfer, Sahil Dagli, David Barton +2
Dynamically reconfigurable metasurfaces promise compact and lightweight spatial light modulation for many applications, including LiDAR, AR/VR, and LiFi systems. Here, we design an…
Thermal conductivity of AlN, GaN, and AlGaN alloys as a function of composition, temperature, crystallographic direction, and isotope disorder from first principles
Sahil Dagli, Kelsey A. Mengle, Emmanouil Kioupakis
Ultra-wide-band-gap group-III nitrides are of interest for applications in deep-ultraviolet optoelectronics and power electronics. Such devices must be able to efficiently dissipat…
