Scattering of the Radial Polarized Beams on the Metal Spherical Particle: Plasmonic Nanojet Formation

D. O. Plutenko et al.

Summary: The photonic nanojet formation on a metallic spherical particle under illumination with a focused light beam with polarization singularity is characterized by radial polarization, strong amplification factor, small transverse size, zero magnetic component on the axis, and longitudinal polarization of the electric field.

Polarization Label-Free Microscopy Imaging of Biological Samples by Exploiting the Zeeman Laser Emission

Fabio Callegari et al.

Summary: Mueller Matrix Microscopy based on a scanning beam architecture utilizing Zeeman laser for simultaneous emission of orthogonal polarization states enables high-speed scanning microscopy without the need for additional active components for polarization state management. The approach is founded on detecting interference signal to time-encode polarization states directly from the laser source.

Poincare Rotator for Vortexed Photons

Shinichi Saito

Summary: The Poincare sphere is used to describe the polarized state of coherent photons, while attention is also given to the Optical Orbital Angular Momentum (OAM) as another fundamental property of photons. A compact Poincare rotator is proposed for controlling vortexed photons in a silicon photonic platform. The impact of geometric phases and conservation laws on vortexed photons is discussed.

Electronic Currents and Magnetic Fields in H 2+Induced by Coherent Resonant Bichromatic Circularly Polarized Laser Pulses: Effects of Orientation, Phase, and Helicity

Andre D. Bandrauk et al.

Summary: Theoretical study on ultrafast magnetic field generation in intense bichromatic circularly polarized laser fields shows that resonant excitation influences the phase and helicity. The generated magnetic field depends on pulse phase, sensitive to molecular alignment and laser polarization. Resonant excitation induces coherent ring electron currents, affecting the phase dependence.

A Bi-Axial Quantum State That Controls Molecular Collisions Like a Double-Slit Interferometer

William E. Perreault et al.

Summary: Researchers used Stark-induced adiabatic Raman passage (SARP) to control molecular scattering of hydrogen molecules, showing molecules moving along defined angles as a result of scattering from a bi-axial state. By experimentally testing theoretical calculations, they demonstrated the ability to measure the relative phases of scattering matrix elements.

Generation of High-Order Vortex States From Two-Mode Squeezed States

Graciana Puentes et al.

Summary: This scheme utilizes two-mode photon-number squeezed states to generate high-order quadrature vortex states, mapping photon-number fluctuations to interference effects in the quadratures. It has the potential to improve measurement sensitivity for applications such as quantum cryptography, quantum metrology, and sensing.
