Optics Express
|March 18, 2022
Summary
Elliptic Gaussian breathers with critical orbital angular momentum (OAM) can form stable spiraling solitons in nonlinear media. This OAM-carrying beam maintains its shape and allows power-controlled rotation, enabling potential all-optical manipulation applications.
Area of Science:
- Nonlinear optics
- Optical beam propagation
- Quantum optics
Background:
- Elliptic Gaussian breathers are complex light structures.
- Nonlocal nonlinear media affect light propagation.
- Orbital angular momentum (OAM) influences beam dynamics.
Purpose of the Study:
- Investigate breather propagation in thermal nonlocal nonlinear media.
- Analyze the role of OAM in beam stability and soliton formation.
- Explore potential applications in all-optical manipulation.
Main Methods:
- Analytical treatment of beam propagation dynamics.
- Experimental observation of breather behavior.
- Characterization of beam parameters like width, intensity, and rotation angle.
Main Results:
- OAM-free elliptic beams oscillate and do not form solitons.
- Elliptic beams with critical OAM form stable spiraling solitons.
- Soliton rotation angle is linearly controlled by input power near critical power.
- Beamwidths and ellipticity remain invariant during propagation.
Conclusions:
- Critical OAM is essential for forming stable elliptic solitons.
- Power-tunable spiraling elliptic solitons offer precise control.
- These findings pave the way for advanced all-optical manipulation technologies.

Physical Principles Governing Gas Exchange
2.2K
Gas behavior plays a vital role in understanding bodily processes such as external and internal respiration. External respiration involves the diffusion of oxygen into the blood and carbon dioxide out of it in the lungs. In contrast, internal respiration happens in body tissues, where these gases move in opposite directions.

The behavior of gases is guided by Dalton's Law of partial pressures and Henry's Law.

Bernoulli's Equation for Flow Normal to a Streamline
982
Bernoulli's equation for flow normal to a streamline explains how pressure varies across curved streamlines due to the outward centrifugal forces induced by the fluid's curvature. The pressure is higher on the inner side of the curve, near the center of curvature, and decreases outward to balance these centrifugal forces.
The pressure difference depends on the fluid's velocity and radius of curvature. The pressure variation is minimal in flows with nearly straight streamlines.

The electric potential of the system can be calculated by relating it to the electric charge densities that give rise to the electric potential. The differential form of Gauss's law expresses the electric field's divergence in terms of the electric charge density.

Bernoulli's Equation for Flow Along a Streamline
1.1K
Bernoulli's equation relates the energy conservation in a fluid moving along a streamline. The equation applies to incompressible and inviscid fluids under steady flow. For such a flow, Newton's second law is applied to a small fluid element, which experiences forces due to pressure differences, gravity, and velocity variations. The force balance leads to the following form of Bernoulli's equation:

Bernoulli's Equation
11.2K
In the middle of the nineteenth century, it was observed that two trains passing each other at a high relative speed get pulled towards each other. The same occurs when two cars pass each other at a high relative speed. The reason is that the fluid pressure drops in the region where the fluid speeds up. As the air between the trains or the cars increases in speed, its pressure reduces. The pressure on the outer parts of the vehicles is still the atmospheric pressure, while the resultant...

Standing Waves in a Cavity
1.1K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:
