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

Chalcogenide glasses (ChGs) excellent optical materials in the infrared range. ChG lens
has important applications in the environmental detection and biochemical imaging field. In …

One of the most significant developments in life sciences—the discovery of bacteria and
protists—was accomplished by Antoni van Leeuwenhoek in the 17th century using a single …

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 develop a hybrid optofluidic microcavity by placing a microsphere with a diameter
ranging from 1 to 4 μm in liquid-filled plano-plano Fabry–Perot (FP) cavities, which can …

Anisotropic wet etching of silicon (Si) has been known for decades, but the extraordinary
capabilities of this technology to provide highly ordered microphotonic arrays have received …

It is widely discussed in the literature that a problem of reduction of thermal noise of mid-
wave and long-wave infrared (MWIR and LWIR) cameras and focal plane arrays (FPAs) can …

Metalenses play an important role in optoelectronic integrated devices, given their
advantages in miniaturization and integration. Due to its high aspect ratio subwavelength …

The sensitivity of infrared (IR) focal plane arrays (FPAs) is often limited by a low pixel fill
factor. Solid immersion microlens arrays address this problem by focusing the light reaching …
