Generation of Color Images by Utilizing a Single Composite Diffractive Optical Element
This paper presents an approach that is capable of producing a color image using a single composite diffractive optical element (CDOE). In this approach, the imaging function of a DOE and the spectral deflection characteristics of a grating were combined

HKUST-1-Doped High-Resolution Volume Holographic Gratings
We report on transmission holographic gratings doped with metal organic frameworks (MOFs). As a first attempt, we focused on MOF-199, also known as HKUST-1, which is an efficient adsorbent of VOCs.

Dual-Wavelength Spectroscopy of a Metallic-Grating-Coupled Surface Plasmon Resonance Biosensor
A novel approach is proposed to decouple the surface and bulk effects in surface plasmon resonance (SPR) biosensors. This method is based on a metallic-grating-based SPR in which a sensor is efficiently optimized to excite three surface plasmon waves at ...

Broadband Mirrors in the Near-Infrared Based on Subwavelength Gratings in SOI
We describe the design, fabrication, and characterization of high-reflectivity broadband mirrors operating in the near-infrared (700-1000 nm) wavelength range.

Protein Binding Detection Using On-Chip Silicon Gratings
We demonstrate a silicon gratings-based biosensor to detect functionalized protein binding on its surface. The designed silicon gratings have sensitivities up to 197 nm/RIU in detecting refractive index change and 1.61 nm per nanometer of thickness ...
