What is fundamental soliton?
A fundamental soliton is an optical pulse which can propagate in a dispersive medium (e.g. an optical fiber) with a constant shape of the temporal intensity profile, i.e., without any temporal broadening as is usually caused by dispersion. The period of their evolution is the so-called soliton period.
What is meant by soliton?
A soliton is a solitary wave that behaves like a “particle”, in that it satisfies the following conditions (Scott, 2005): It must maintain its shape when it moves at constant speed. When a soliton interacts with another soliton, it emerges from the “collision” unchanged except possibly for a phase shift.
What are solitons what are its features?
Two continuous-wave lasers are used as light source. The soliton crystal exhibits features of a linear and nonlinear optical pattern at the same time and is insensitive to the initial laser power fluctuations. We perform our studies using the numerical technique called Soliton Radiation Beat Analysis.
What are the types of solitons?
They exhibit the most famous solitons: the KdV (pulse) solitons, the sine-Gordon (topolog- ical) solitons and the envelope (or NLS) solitons. All the solitons are one- dimensional (or quasi-one-dimensional). Figure . 7 schematically shows these three types of solitons.
Do solitons exist?
Other solitons occur as the undersea internal waves, initiated by seabed topography, that propagate on the oceanic pycnocline. Atmospheric solitons also exist, such as the morning glory cloud of the Gulf of Carpentaria, where pressure solitons traveling in a temperature inversion layer produce vast linear roll clouds.

What are the properties of solitons?
15) ascribe three properties to solitons:
- They are of permanent form;
- They are localized within a region;
- They can interact with other solitons, and emerge from the collision unchanged, except for a phase shift.
