Kavli Affiliate: N. C. Yeh | First 5 Authors: C. -C. Hsu, M. L. Teague, J. -Q. Wang, N. -C. Yeh, | Summary: The existence of nontrivial Berry phases associated with two inequivalent valleys in graphene provides interesting opportunities for investigating the valley-projected topological states. Examples of such studies include observation of anomalous quantum Hall […]

Kavli Affiliate: James J. Bock | First 5 Authors: Yun-Ting Cheng, Tzu-Ching Chang, James J. Bock, , | Summary: Line intensity mapping (LIM) is a promising tool to efficiently probe the three-dimensional large-scale structure by mapping the aggregate emission of a spectral line from all sources that trace the matter density field. Spectral lines from […]

Kavli Affiliate: Oskar Painter | First 5 Authors: Eunjong Kim, Xueyue Zhang, Vinicius S. Ferreira, Jash Banker, Joseph K. Iverson | Summary: While designing the energy-momentum relation of photons is key to many linear, non-linear, and quantum optical phenomena, a new set of light-matter properties may be realized by employing the topology of the photonic […]

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Huanhao Li, Zhipeng Yu, Yunqi Luo, Shengfu Cheng, Lihong V. Wang | Summary: Speckles arise when coherent light interacts with biological tissues. Information retrieval from speckles is desired yet challenging, requiring understanding or mapping of the multiple scattering process, or reliable capability to reverse or compensate […]

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 […]
