Silicon nitride (Si3N4) subwavelength medium contrast gratings (MCGs) directly integrated with CMOS photodetectors are a promising option for on-chip label-free biosensing. The narrow spectral features required for sensing ...

Certain metallic nanostructures exhibiting localized surface plasmon resonances (LSPR) are capable of sensing extremely low-volume analytes down to attoliters, especially when used in a single particle configuration. ...

The strong dispersion, ultra-thin form-factor and robustness to degradation make metasurfaces attractive for color filter applications. In particular, transmission-mode filters using silicon could potentially replace ...
