Abstract High-quality optical ring resonators can confine light in a small volume and store it for millions of roundtrips. They have enabled the dramatic size reduction from laboratory scale to chip level of optical filters, modulators, frequency con

Cluster synchronization is a general phenomenon in a network of non-locally coupled oscillators. Here, we show that cluster synchronization occurs in semiconductor lasers, where the beat notes between the pairs of adjacent longitudinal modes of the l

Abstract Phase singularities are loci of darkness surrounded by monochromatic light in a scalar field, with applications in optical trapping, super-resolution imaging, and structured light-matter interactions. Although 1D singular structures, like op

Abstract Dispersion results from the variation of index of refraction as well as electric field confinement in sub-wavelength structures. It usually results in efficiency decrease in metasurface components leading to troublesome scattering into unwan

Microcavities concentrate light in tiny volumes and are important, e.g., for semiconductor lasers and nonlinear optics. In this paper, metasurfaces are introduced to realize microcavities with arbitrary mode profiles.

Resonators are key components in optics. In this work, the authors introduce a class of optical resonators with distinctly different properties from conventional resonators, allowing fundamental design trade-offs to be circumvented.

Active photonics in free space is important in computing, imaging and sensing. Here, hybrid silicon-organic nanoscale structures change the intensity of a free-space light beam by applied microwave signals at gigahertz speeds with a high efficiency.

Abstract Meta-optics has achieved major breakthroughs in the past decade; however, conventional forward design faces challenges as functionality complexity and device size scale up. Inverse design aims at optimizing meta-optics design but has been cu
