Metasurface-Tunable Lasing Polarizations in Microcavity
, 2023 Manipulating polarization states of microlasers is essentially important in many emerging optical and biological applications. Strategies have been focused on using external optical elements or surface nanostructure to control the polarization state of ...

Parametric Testing of Metasurface Stirrers for Metasurfaced Reverberation Chambers [PDF]
Sensors, 2019 In this paper, the correlation coefficients and the total scattering cross sections (TSCSs) for different types of metasurfaced stirrers and the traditional metallic stirrer, and the effects on field uniformity when such stirrers are used in reverberation chambers, are analyzed.

Metasurface-Stabilized Optical Microcavities
, 2022 We demonstrate stable optical microcavities by counteracting the phase evolution of the cavity modes using an amorphous silicon metasurface as one of the two cavity end mirrors.

Metasurface-dressed two-dimensional on-chip waveguide for free-space light field manipulation
, 2022 We show that a metasurface-coated two-dimensional (2D) slab waveguide enables the generation of arbitrary complex light fields by combining the extreme versatility and freedom on wavefront control of optical metasurfaces with the compactness of photonic ...

Metasurface-Based Realization of Photonic Time Crystals
, 2022 Photonic time crystals are artificial materials whose electromagnetic properties are uniform in space but periodically vary in time. The synthesis of such materials and experimental observation of their physics remain very challenging.

Coherent retroreflective metasurfaces [PDF]
Physical Review Research, 2021 Inhomogeneous metasurfaces have shown possibilities for unprecedented control of wave propagation and scattering. While it is conventional to shine a single incident plane wave from one side of these metastructures, illuminating by several waves simultaneously from both sides may enhance possibilities to control scattered waves, which results in ...

Mechanochromic Reconfigurable Metasurfaces [PDF]
Advanced Science, 2019 AbstractThe change of optical properties that some usually natural compounds or polymeric materials show upon the application of external stress is named mechanochromism. Herein, an artificial nanomechanical metasurface formed by a subwavelength nanowire array made of molybdenum disulfide, molybdenum oxide, and silicon nitride changes color upon ...
