The main purpose of the paper is to present the impact of the polarization state of light in fiber optic interference sensors on their stability and efficiency. The main application of interference-based sensors for security is the protection of wide area objects, especially perimeter protection. This type of sensor offers high accuracy of locating disturbances and a high certainty of detection...

Intersubband emission in double-well structures with quantum interference in absorption We investigate the light propagation and dynamical control of a weak pulsed probe field in asymmetric double quantum wells via Fano interference, which is caused by tunneling from the ex...

We have observed spatial confinement of laser light in micrometer-sized random media. The optical confinement is attributed to the disorder-induced scattering and interference. Our experimental data suggest that coherent amplification of the scattered light enhances the interference effect and helps the spatial confinement. Using the finite-difference time-domain method, we simulate lasing with...

For the Standard Model extended with a real scalar singlet field, the modification of the heavy Higgs signal due to interference with the continuum background and the off-shell light Higgs contribution is studied for gg → ZZ,WW → 4 lepton processes at the Large Hadron Collider. Interference effects can range from O(10%) to O(1) effects for integrated cross sections. Despite a strong cancellatio...

We report experimental and theoretical verification of the nature and position of multiple interference points of visible light transmitted through the valve of the centric diatom species Coscinodiscus granii. Furthermore, by coupling the transmitted light into an optical fiber and moving the diatom valve between constructive and destructive interference points, an extinction ratio of 20 dB is ...

Is light a wave or a particle? The Dutch physicist Christiann Huygens (1629-1695) advocated that light was a wave. Huygens principle is often used to describe how waves in general propagate. In 1704 Newton published the first edition of his book Optiks in which he championed the notion that light consisted of particles which we now call photons. Thomas Young performed a two slit interference ex...

Supernumerary arcs on rainbows are historically important because in the early 1800s they provided evidence in favor of the wave theory of light. The success of Airy's rainbow integral has overshadowed the earlier contribution from Young, who proposed that supernumerary arcs were caused by interference between two geometrical rays that emerge from the raindrop at the same scattering angle. Airy...
