We present a compact and multi-resonant aperture system supporting large local electromagnetic fields, which is highly advantageous for applications demanding high signal-to-noise ratio. The system is composed of subwavelength H-shaped apertures with exten ...
Mid-infrared absorption spectroscopy is a powerful tool for optically probing the molecular structure of biological samples. However, using conventional approaches, IR measurements on small quantities of molecules are extremely challenging due to sensitivi ...
Recently, bowtie-shaped apertures have received significant attention due to their extraordinary ability to generate dramatic field enhancement and light confinement in nanometer scale. In this article, we investigate both experimentally and theoretically ...
We will demonstrate plasmonic and metamaterial based integrated nano-biosensors and ultrasensitive infrared absorption spectroscopy. These systems by enabling monitoring of molecular-protein interactions in real-time within aqueous solutions can be importa ...
