In recent years, vortex beams with orbital angular momentum (OAM) have attracted more
and more attention. The wavefront of the OAM beams is helical, the intensity at the center of …

Providing much-needed information on fluorescence spectroscopy and microscopy, this
ready reference covers detection techniques, data registration, and the use of spectroscopic …

We present a new method to measure absolute diffusion coefficients at nanomolar
concentrations with high precision. Based on a modified fluorescence correlation …

Hall effect of light is a result of symmetry breaking in spin and/or orbital angular momentum
(OAM) possessing optical system and is caused by eg refractive index gradient/interface …

Quantum correlation of two‐photon states is utilized to suppress the environmental noise in
imaging down to the single‐photon level. However, the size of the coherence area of the …

Several works on optical higher-order differential operations have recently attracted
attention, particularly in image processing for edge detection. However, the inefficient …

The scarcity of RF spectrum at lower frequencies has recently been addressed by millimeter
wave transmission in fiber-wireless and radio-over-free-space optics networks for more …

For practical wireless communication links, one of the critical challenges is the random
fluctuation of turbulence that will impair link performance. Here a transmission model of …

In this work, we have demonstrated mode division multiplexing (MDM) based high-speed
passive optical network (PON) and free-space optical (FSO) hybrid link for providing a …

We derive explicit analytical relations to describe paraxial light beams that represent a
particular case of the hypergeometric (HyG) laser beams [J. Opt. Soc. Am. A25, 262-270 …
