We observe high optical quality factor (Q) polygonal and star coherent optical modes in a lithium niobate microdisk. In contrast to the previous polygon modes achieved by deformed microcavities at lower mechanical and optical Q, we adopted weak pertu

Thin large microdisks, that are key to dense spectral microcomb generation at visible‐to‐UV wavelengths, face challenges in fabrication. One of the most difficult issues is the buckling effect that makes comb generation infeasible due to the seve

An ultra-broadband absorber of light is proposed by using periodic array of ultra-thin metallic ribbons on top of a lossless quarter-wavelength dielectric spacer placed on a metallic reflector. We propose a fully analytical circuit model for the stru

The scattering of graphene surface plasmons normally incident on a line discontinuity in graphene surface conductivity is investigated. The effect of the length of the transition region on the reflection and transmission coefficients is studied. It i

Considering graphene metasurfaces as shunt admittance sheets, we propose a transmit-array configuration which can mold incident beam by modulating wavefront phase and amplitude. Thanks to the exceptional properties of graphene ribbons such as tunabli

Scattering of graphene surface plasmons that are obliquely incident on a line discontinuity in graphene surface conductivity is investigated. The analysis is based on a solution of the quasi-static integral equation for surface charge density. It is

We propose an unprecedented transmit-array configuration which can mold the incident beam by modulating phase and amplitude wavefronts. The transmit-array is composed of patterned graphene metasurfaces as shunt admittance sheets. Thanks to the except
