Optics Express
|October 12, 2022
Summary
We numerically investigate optical information transfer using atomic vapor. Vectorial light structure transfers from control to probe beams, but diffraction causes separation at longer distances.
Area of Science:
- Atomic, Molecular, and Optical Physics
- Quantum Optics
- Nonlinear Optics
Background:
- Atomic vapors can act as nonlinear optical media.
- Vector vortex beams possess structured polarization.
- Light propagation in atomic systems involves complex interactions.
Purpose of the Study:
- To numerically investigate optical information transfer from a control beam to a probe beam.
- To understand the role of atomic vapor as a mediating medium.
- To explore the influence of propagation distance on information transfer.
Main Methods:
- Numerical modeling of light field propagation.
- Simulation of a double-V atomic system in cold rubidium.
- Analysis of polarization dynamics and spatial separation.
Main Results:
- Vectorial light structure is transferred from control to probe beams over short distances.
- Diffraction leads to spatial separation of probe beam components at longer distances.
- Four-wave mixing establishes correlations between polarization structure and diffraction.
Conclusions:
- Atomic vapor enables optical information transfer, but diffraction limits fidelity over distance.
- Coupled dynamics of internal and external degrees of freedom are generated.
- The study provides insights into light-matter interactions in structured light fields.

Potential Due to a Polarized Object
460
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...

Atomic Nuclei: Nuclear Relaxation Processes
706
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis.

Dielectric Polarization in a Capacitor
4.9K
The presence of a dielectric medium in a capacitor not only changes the voltage and capacitance but also affects the electric field. In general, dielectrics can be of two types: polar and nonpolar. In a polar dielectric, the positive and negative charges in the molecules are separated by a distance and hence have a permanent dipole moment. In contrast, no such charge separation exists in a nonpolar dielectric, however the nonpolar molecules get polarized in the presence of an external electric...

¹H NMR: Interpreting Distorted and Overlapping Signals
1.1K
Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)
1.1K
When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...

Double Resonance Techniques: Overview
268
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
