Materials with relatively small refractive indices (n< 2), such as glass, quartz, polymers,
some ceramics, etc., are the basic materials in most optical components (lenses, optical …

The photonic nanojet (PNJ) is a narrow high-energy beam that was originally found on the
back side of all-dielectric spherical structures. It is a unique type of energy concentration …

We demonstrate a camera which can image methane gas at video rates, using only a single-
pixel detector and structured illumination. The light source is an infrared laser diode …

Optical components based on metasurfaces (metalenses) offer an alternative methodology
for microlens arrays. In particular, metalens arrays have the potential of being monolithically …

This work takes inspiration from chemistry where the spectral characteristics of the
molecules are determined by hybridization of electronic states evolving from the individual …

Metasurfaces and, in particular, metalenses have attracted large interest and enabled
various applications in the near-infrared and THz regions of the spectrum. However, the …

Polarization-independent dielectric meta-lens is proposed to monolithically integrate with a
HgCdTe infrared photodetector to concentrate power flux into a reduced photosensitive area …

We demonstrate an InAsSb nBn detector monolithically integrated with a microlens
fabricated on the back side of the detector. The increase in the optical collection area of the …

Infrared imaging technology has been a worldwide research focus with various significant
applications in the military and surveillance fields. Due to the complicated structure of the …
