Kavli Affiliate: Andrei Faraon | First 5 Authors: Amir Arbabi, Ehsan Arbabi, Mahdad Mansouree, Seunghoon Han, Seyedeh Mahsa Kamali | Summary: One of the important advantages of optical metasurfaces over conventional diffractive optical elements is their capability to efficiently deflect light by large angles. However, metasurfaces are conventionally designed using approaches that are optimal for […]

Kavli Affiliate: Oskar Painter | First 5 Authors: Mohammad Mirhosseini, Alp Sipahigil, Mahmoud Kalaee, Oskar Painter, | Summary: Bidirectional conversion of electrical and optical signals lies at the foundation of the global internet. Such converters are employed at repeater stations to extend the reach of long-haul fiber optic communication systems and within data centers to […]

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Szilard Szoke, Hanzhe Liu, Bryce P. Hickam, Manni He, Scott K. Cushing | Summary: Entangled photons exhibit non-classical light-matter interactions that create new opportunities in materials and molecular science. For example, in entangled two-photon absorption, the intensity-dependence scales linearly as if only one photon was present. […]

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Chengying Bao, Myoung-Gyun Suh, Boqiang Shen, Kemal Şafak, Anan Dai | Summary: Coherently-pumped (Kerr) solitons in an ideal optical microcavity are expected to undergo random quantum motion that determines fundamental performance limits in applications of soliton microcombs. Here, this diffusive motion and its impact on Kerr […]

Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Chengying Bao, Boqiang Shen, Myoung-Gyun Suh, Heming Wang, Kemal Safak | Summary: Both the group velocity and phase velocity of two solitons can be synchronized by a Kerr-effect mediated interaction, causing what is known as soliton trapping. Trapping can occur when solitons travel through single-pass optical […]

Kavli Affiliate: Andrei Faraon | First 5 Authors: Philip Camayd-Muñoz, Conner Ballew, Gregory Roberts, Andrei Faraon, | Summary: Three-dimensional elements, with refractive index distribution structured at sub-wavelength scale, provide an expansive optical design space that can be harnessed for demonstrating multi-functional free-space optical devices. Here we present 3D dielectric elements, designed to be placed on […]

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Laura Kim, Seyoon Kim, Pankaj K. Jha, Victor W. Brar, Harry A. Atwater | Summary: The decay dynamics of excited carriers in graphene have attracted wide scientific attention, as the gapless Dirac electronic band structure opens up relaxation channels that are not allowed in conventional materials. […]

Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Vinicius S. Ferreira, Jash Banker, Alp Sipahigil, Matthew H. Matheny, Andrew J. Keller | Summary: A structured electromagnetic reservoir can result in novel dynamics of quantum emitters. In particular, the reservoir can be tailored to have a memory of past interactions with emitters, in contrast to memory-less […]

Kavli Affiliate: M. Gharib | First 5 Authors: E. F. Schibber, D. R. Mittelstein, M. Gharib, M. G. Shapiro, P. P. Lee | Summary: The method of oncotripsy, first proposed in [S. Heyden and M. Ortiz (2016). Oncotripsy: Targeting cancer cells selectively via resonant harmonic excitation. Journal of the Mechanics and Physics of Solids, 92:164-175], […]

Kavli Affiliate: Michael Roukes | First 5 Authors: Olli-Pentti Saira, Matthew H. Matheny, Libin Wang, Jukka Pekola, Michael Roukes | Summary: Weak electron-phonon interaction in metals at low temperatures forms the basis of operation for cryogenic hot-electron bolometers and calorimeters. Standard power laws, describing the heat flow in the majority of experiments, have been identified […]
