This article presents a review on the current status, challenges, and potential future
development opportunities for HgCdTe infrared materials and detector technology. A brief …

Dielectric and metallic gratings have been studied for more than a century. Nevertheless,
novel optical phenomena and fabrication techniques have emerged recently and have …

A broadband absorber based on a tapered, alternating metal–dielectric multilayered
structure was realized in the visible and IR range. The structure is fabricated by using a …

Arrays of plasmonic nanocavities with very low volumes, down to λ3/1000, have been
fabricated by soft UV nanoimprint lithography. Nearly perfect omnidirectional absorption (3 …

Surface plasmon resonance (SPR) has been intensively studied and widely employed for
light trapping and absorption enhancement. In the mid-infrared and terahertz (THz) regime …

High temporal and spatial coherent simultaneous long-wavelength/mid-wavelength
(LW/MW) two-color focal plane array (FPA) infrared detection is the cutting-edge technique …

III–V semiconductor mid-infrared photodetectors based on intersubband transitions hold
great potential for ultra-high-speed operation up to several hundreds of GHz. In this work we …

Optical patch antennas sandwiching dielectrics between metal layers have been used as
deep subwavelength building blocks of metasurfaces for perfect absorbers and thermal …

We study the quality factor variation of three-dimensional Metal-Insulator-Metal
nanoresonators when their volume is shrunk from the diffraction limit (λ/2n)^ 3 down to a …

Infrared (IR) technology plays a significant role in many application scenarios, such as
satellite remote sensing, environmental monitoring, biomedical engineering, imaging …
