Fabrication tolerance impact on BIC metasurface resonances
2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2021Photonic bound states in the continuum (BICs) have recently emerged as an exciting toolkit for all-dielectric metasurfaces with sharp resonances and strong near-field enhancements. Specifically, metasurface unit cells with broken in-plane symmetry have unlocked precise control over the linewidth and therefore the quality factor (Q factor) of BIC-based ...

3D fabrication for optical metamaterials and metasurfaces
2016 Progress in Electromagnetic Research Symposium (PIERS), 2016Metamaterials enable the engineering of refractive index into the intriguing negative regime. Such negative index metamaterials (NIMs) can give rise to unique optical properties like negative refraction and backward waves. Similarly, zero index metamaterials (ZIMs) are widely studied recently for they open a new route to realize uniform phase ...

Fabrication of plasmonic metasurfaces for fluorescence nanoscopy
2023Single-molecule fluorescence localization microscopy has become an indispensable technique of imaging with resolution better than 10 nanometers. However, the light emission of fluorophores is not easy to control because of photobleaching. In the presence of nanoantennas, the photobleaching lifetime, blinking rate and overall photoluminescence intensity
