|January 12, 2008
Summary
The soliton internal mode explains long-lived oscillations in self-guided beams. This mode significantly impacts beam propagation in non-Kerr media, causing output width to oscillate with input power.
Area of Science:
- Nonlinear optics
- Mathematical physics
Background:
- Self-guided beams, or spatial solitons, exhibit long-lived oscillations.
- Understanding the dynamics of these solitons is crucial for optical applications.
Purpose of the Study:
- To introduce the concept of soliton internal mode.
- To quantitatively explain the oscillations of breathing spatial solitons.
- To investigate the effect of the internal mode on beam propagation in non-Kerr media.
Main Methods:
- Theoretical analysis of soliton internal mode.
- Detailed consideration of cubic-quintic nonlinearity.
- Investigation of beam propagation in non-Kerr media.
Main Results:
- The soliton internal mode quantitatively explains long-lived oscillations.
- The internal mode strongly affects beam propagation in non-Kerr media.
- Oscillatory dependence of output beam width on input power was observed.
Conclusions:
- The soliton internal mode is a key concept for understanding spatial soliton dynamics.
- Non-Kerr media exhibit complex beam propagation behavior influenced by the internal mode.
- This finding has implications for controlling and predicting soliton behavior in optical systems.

01:28Standing Waves in a Cavity
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:
01:05Breathing
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
00:51Speed of Sound in Solids and Liquids
Most solids and liquids are incompressible—their densities remain constant throughout. In the presence of an external force, the molecules tend to restore to their original positions, which is only possible because the constituents interact. The interactions help the constituents pass on information about external disturbances, like sound waves. Therefore, sound waves travel faster through these media. Compared to solids, the constituents in a liquid are less tightly bound. Thus, sound waves...
01:28Adsorption of Gases on Solids
Adsorption is a process where molecules, known as the adsorbates, accumulate on a surface, which is referred to as the adsorbent or substrate. Occurring at the solid-gas interface, this phenomenon is crucial in various scientific and industrial contexts. The reverse of adsorption is desorption.Two types of adsorptions exist: physical (physisorption) and chemical (chemisorption). Physisorption involves gas molecules held to the solid's surface by relatively weak intermolecular van der Waals...
01:01Energy Bands in Solids
Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states that no two...

01:22Couette Flow
Couette flow represents the flow of fluid between two parallel plates, with one plate fixed and the other moving with a constant velocity. This configuration allows for a simplified analysis using the Navier-Stokes equations, which govern fluid motion under conditions of viscosity and incompressibility. For Couette flow, the assumptions include a steady, laminar, incompressible flow with a zero-pressure gradient in the flow direction. This flow type is beneficial for understanding shear-driven...
