In this letter, we design a terahertz (THz) multi-band absorber comprised of four square
open/closed loops and a ring wall resonant metamaterial with a high absorption rate for TE …

Pixelated filter arrays of Fabry-Perot (FP) cavities are widely integrated with photodetectors
to achieve a WYSIWYG (“what you see is what you get”) on-chip spectral measurements …

By combining nanosphere lithography with oblique angle deposition, large-area asymmetric
compound Ag nanohole arrays with nanorods inside the hole were patterned on substrates …

We present three designs of tunable and polarization-sensitive infrared (IR) metamaterials
(PSIMs). They are composed of serpentine-shaped Au nanostructures and denoted as PSIM …

Simultaneously identifying the composition of mixtures and determining their concentration
levels has aroused much attention in recent years to meet the large demands of compact …

Angle-insensitive and high-transmission infrared spectral filters, comprising periodic quasi-
three-dimensional (quasi-3D) nanopost arrays, are fabricated using a nanoimprint …

Metasurface-based terahertz absorbers have recently gained much attention in research on
terahertz devices. However, the actual applications of such absorbers are severely …

The complex Ag nanohole structures with an Ag nanorod inside the hole are designed and
investigated both numerically and experimentally. Based on finite-difference-time-domain …

We present the design and fabrication results for wavelength tuning of InAs/GaSb type-II
superlattice spectral response based on square coaxial aperture array at mid-wave infrared …

We fabricated and characterized three types of nanostructures for photonic applications.
Gold structures were used for light filtering in the infrared spectral region as well as for …
